Abstract — Self-Organizing Maps (SOM) are considered by many to be black boxes because the results are often non-intuitive. Our research takes the multidimensional output from a successful intrusion detecting SOM and displays it in novel full color and 3D formats, with landscape features similar to an island, that assist in understanding the SOM results. This paper describes the visual data mining from the map and explains the methodology in obtaining the full color and 3D maps.

Abstract - Developing smart house systems has been a great challenge for researchers and engineers in this area because of the high cost of implementation and evaluation process of these systems, while being very time consuming. Testing a designed smart house before actually building it is considered as an obstacle towards an efficient smart house project. This is because of the variety of sensors, home appliances and devices available for a real smart environment. In this paper, we present the design and implementation of a multi-purpose smart house simulation system for designing and simulating all aspects of a smart house environment. This simulator provides the ability to design the house plan and different virtual sensors and appliances in a two dimensional model of the virtual house environment. This simulator can connect to any external smart house remote controlling system, providing evaluation capabilities to their system much easier than before. It also supports detailed adding of new emerging sensors and devices to help maintain its compatibility with future simulation needs. Scenarios can also be defined for testing various possible combinations of device states; so different criteria and variables can be simply evaluated without the need of experimenting on a real environment.

Abstract— The combination of Multi-Input Multi-Output (MIMO) with Orthogonal Frequency Division Multiplexing (OFDM) is regarded as a winning technology for future broadband communication. However, its sensitivity to Carrier Frequency Offset (CFO) is a major contributor to the Inter-Carrier Interference (ICI), this effect becomes more severe by the presence of multipath fading in wireless channels. This paper is concerned with CFO estimation for MIMO-OFDM system. The presented algorithm uses a two-step strategy. In the proposed method a preamble structure is used which made up of repeated orthogonal polyphase sequences such as Zadoff and Chu sequences. Both of them belong to the class of Constant Amplitude Zero Auto-Correlation (CAZAC) sequences. The repeated preambles that are constructed using a CAZAC code are simultaneously transmitted from all transmit antennas to accomplish frequency offset estimation. Simulation results show the robustness, accuracy and time-efficiency of the proposed algorithm compared to existing similar algorithms that use PN codes especially in multi-path channel.

Abstract— Ad-hoc networks are a collection of mobile hosts that communicate with each other without any infrastructure. These networks are vulnerable against many types of attacks including black hole. In this paper, we analyze the effect of this attack on the performance of ad-hoc networks using AODV as a routing protocol. Furthermore, we propose an approach based on hash chain to prevent this type of attack. Simulation results using OPNET simulator depicts that packet delivery ratio, in the presence of attacker nodes, reduces remarkably. On the other hand, applying proposed approach can reduce the effect of black hole attacks.

Abstract— As the web grows and the amount of traffics on the web server increase, problems related to performance begin to appear. Some of the problems, such as the number of users that can access the server simultaneously, the number of requests that can be handled by the server per second (requests per second) to bandwidth consumption and hardware utilization like memories and CPU. To give better quality of service (QoS), web hosting providers and also the system administrators and network administrators who manage the server need a benchmark application to measure the capabilities of their servers. Later, the application intends to work under Linux/Unix – like platforms and built using Erlang/OTP R11 as a concurrent oriented language under Fedora Core Linux 5.0. It is divided into two main parts, the controller section and the launcher section. Controller is the core of the application. It has several duties, such as read the benchmark scenario file, configure the program based on the scenario, initialize the launcher section, gather the benchmark results from local and remote Erlang node where the launcher runs and write them in a log file (later the log file will be used to generate a report page for the sysadmin). Controller also has function as a timer which act as timing for user inters arrival to the server. Launcher generates a number of users based on the scenario, initialize them and start the benchmark by sending requests to the web server. The clients also gather the benchmark result and send them to the controller.

Abstract— Mobile ad hoc network is a self-organizing and self-configuring network in which, mobile host moved freely, due to this disconnection is often occurred between mobile hosts. In mobile ad hoc network location of mobile nodes are frequently changed. Location management is a crucial issue in MANET due to dynamic topologies. In this paper we propose a position based routing scheme called “Concentric Circular Quadrant Routing Scheme (CCQRS)”. In this paper we use single location server region for location update and location query. This strategy reduces the cost associated with location update and location query.

Abstract— The main aim of future wireless multimedia networks is to provide sufficient amount of resource to a multimedia call. Reserving required amount of resource in advance to a future new and handoff call is better than rejecting a call at neck of the moment due to insufficient resource at a particular time. This paper presents an efficient handoff resource management strategy by considering the future resource demands of a wireless multimedia call. Here a novel wiener based resource estimation and reservation method is adopted to estimate the instantaneous resource demands of a mobile user. Cell segmentation technique is introduced and utilized to predict the resource demands more accurately in a real time manner. The performance result shows this synergy of resource reservation using pilot sensing and cell segmentation have been decrease the call dropping probability of the handoff calls and increases the micro and pico cellular system performance in real time environments.

Abstract - Email authorship identification helps tracking fraudulent emails. This research proposes extraction on unique words from the emails. These unique words will be used as representative features to train Radial Basis function (RBF). Final weights are obtained and subsequently used for testing. The percentage of identification of email authorship depends upon number of RBF centers and the type of functional words used for training RBF. One hundred fifty authors with one hundred files from the sent folder of Enron database are considered. A total of 300 unique words of number of characters in each word ranging from 3 to 7 are considered. Training and Testing RBF are done by taking different length of words. The percentage of authorship identification ranges from 95% to 97%. Simulation shows the effectiveness of the proposed RBF network for email authorship identification.

Abstract-Concatenated continuous phase modulation (CCPM) facilitates powerful error correction. CPM also has the advantage of being bandwidth efficient and compatible with non-linear amplifiers. Bandwidth efficient concatenated coded modulation schemes were designed for communication over Additive White Gaussian noise (AWGN), and Rayleigh fading channels. An analytical bounds on the performance of Serial (SCCC), and Parallel convolutional concatenated codes (PCCC) were derived as a base of comparison with the third category known as hybrid concatenated convolution codes scheme (HCCC). An upper bound to the soft-input, soft-output (SISO) maximum a posteriori (MAP) decoding algorithm applied to CC's of the three schemes was obtained. Design rules for the parallel, outer, and inner codes that maximize the interleaver's gain were discussed. Finally, a low complexity iterative decoding algorithm that yields a better performance is proposed.

Abstract— We define a priority based mobile transaction scheme in which mobile users can share data stored in the cache of a mobile agent which is a special mobile node for coordinating the sharing process. This framework allows mobile affiliation work group to be formed dynamically with a mobile agent and mobile hosts. Using short range wireless communication technology, mobile users can simultaneously access the data from the cache of the mobile agent. Data Access Manager module at the mobile agent enforces concurrency control using cache invalidation technique. Four levels of priority are assigned to the requesting mobile nodes based on available energy and connectivity. This model supports disconnected mobile computing by allowing mobile agent to move along with the Mobile Hosts. The proposed Transaction frame work has been simulated in J2ME and NS2 and performance of this scheme is compared with existing frame works.

Abstract - The existing Information Retrieval (IR) systems which are based entirely on syntactic (keyword based) contents have serious limitations like irrelevant document retrieval, word sense ambiguity, low precision and recall ratio since the complete semantics of the contents are not represented. To overcome these limitations, from the recent literature it is identified that it is necessary to analyze and determine the semantic features of both the content in document and query. Hence in this paper it is proposed to initially develop a semantic pattern that represents semantic features of the contents in every document in the corpus as a Term Document Matrix (TDM) format. Then to develop a semantic pattern for the contents in the query by incorporating it with Natural Language Processing technique along with Synset (WordNet) for query refinement & expansion. Now the similarity between the semantic pattern of the query and TDM is calculated using Latent Semantic Analysis (LSA) and plotted in Semantic Vector Space. Then by matching against the vector space, contents associated to the query can be identified in the corresponding cluster. Various experimental results are carried on, which shows the increase in document retrieval recall and precision rates, thereby demonstrating the effectiveness of the model.

Abstract— Excessive load on the MANET is the main reason for link breakage and performance degradation. A congested node in the network dies more quickly than other nodes. A good load balancing technique share the traffic load evenly among all the nodes those can take part in transmission. Transferring of load from congested nodes to less busy nodes and involvement of other nodes in transmission that can take part in route can improve the overall network life. We proposed a load balancing scheme for AODV that improves overall network life, throughput and reduce average end to end delay.

Abstract— In this paper we propose Speaker Identification using four different Transform Techniques. The feature vectors are the row mean of the transforms for different groupings. Experiments were performed on Discrete Fourier Transform (DFT), Discrete Cosine Transform (DCT), Discrete Sine Transform (DST) and Walsh Transform (WHT). All the Transform give an accuracy of more than 80% for the different groupings considered. Accuracy increases as the number of samples grouped is increased from 64 onwards. But for groupings more than 1024 the accuracy again starts decreasing. The results show that DST performs best. The maximum accuracy obtained for DST is 96% for a grouping of 1024 samples while taking the transform.

The performance in terms of bit error rate (BER) is evaluated through simulations. The corresponding BER of the concatenated STTuC-STBC-MC-CDMA system is compared with STTuC-MC-CDMA system and STBC-MC-CDMA system. The simulation results show that the STTuC-MCCDMA system performance is better the STBC-MC-CDMA system and it can be further improved by employing concatenation technique i.e. STTuC-STBC-MC-CDMA system.

Abstract— Feature extraction is often applied in machine learning to remove distracting variance from a large and complex dataset, so that downstream classifiers or regression estimators can perform better. The computational expense of subsequent data processing can be reduced with a lower dimensionality. Reducing data to two or three dimensions facilitates visualization and further analysis by domain experts. The data components (parameters) measured in computer assisted semen analysis have complicated correlations and their total number is also large. This paper presents Principal Component Analysis to decorrelate components, reduce dimensions and to extract relevant features for classification. It also compares the computation of Principal Component Analysis using the Covariance method and Correlation method. Covariance based Principal Component Analysis was found to be more efficient in reducing the dimensionality of the feature space.

Abstract— Lossy compression techniques are more efficient in terms of storage and transmission needs. In the case of Lossy compression, image characteristics are usually preserved in the coefficients of the domain space in which the original image is transformed. For transforming the original image, a simple but efficient wavelet transform used for image compression is called Haar Wavelet Transform. The goal of this paper is to achieve high compression ratio in images using 2 D Haar Wavelet Trnasform by applying different compression thresholds for the wavelet coefficients and these results are obtained in fraction of seconds and thus to improve the quality of the reconstructed image ie., to arrive at an approximation of our original image. Another approach for lossy compression is, instead of transforming the whole image, to separately apply the same transformation to the regions of interest in which the image could be devided according to a predetermined characteristic. The Objective of the paper deals to get the coefficients is nearly closer to zero. More specifically, the aim of the thesis is to exploit the correlation characteristics of the wavelet coefficients as well as second order characteristics of images in the design of improved lossy compression systems for medical images. Here a modified simple but efficient calculation schema for Haar Wavelet Transform.

Abstract— The problem of mining temporal association rules from temporal dataset is to find association between items that hold within certain time intervals but not throughout the dataset. This involves finding frequent sets that are frequent at certain time intervals and then association rules among the items present in the frequent sets. In fuzzy temporal datasets as the time of transaction is imprecise, we may find set of items that are frequent in certain fuzzy time intervals. We call these as fuzzy locally frequent sets and the corresponding associated association rules as fuzzy local association rules. These association rules cannot be discovered in the usual way because of fuzziness involved in temporal features. In this paper, we propose a modification to the well-known A-priori algorithm to compute fuzzy locally frequent sets. Finally we have shown manually with the help of an example that the algorithm works.

Abstract— This paper aims to examine how the sensor information can be shared, through a new resource called “cloud”. The recent research issue in integrating Wireless sensor Networks with Cloud is to establish a faster communication link between the two. The wireless sensor networks are used to sense and collect information required. The sensor information is deployed into the cloud through the sensor profile for web services. The Sensor Profile for Web Services specifies a lightweight subset of the overall Web services protocol suite that is appropriate for network-connected sensors. Cloud generally offers resources on demand. Since wireless sensor networks are limited in their processing power, battery life and communication speed, cloud computing usually offers the opposite, which makes it attractive for long term observations, analysis and use in different kinds of environments. In this paper a model is presented, which combines the concept of wireless sensor networks with the cloud computing paradigm, and show how both can benefit from this combination. Sensor data access is thus moved from loosely managed system to a well managed cloud. The integration of sensor information into the cloud through the sensor as a service paradigm proves the faster communication establishment. The scalability of this approach seems to be unlimited, since wireless sensor networks operate independently, and are connected to the cloud computing environment through a scalable number of wireless sensor network communication gateways. The cloud computing environment itself offers a scalable infrastructure, which makes it very attractive. The main goal is to design a flexible architecture in which sensor network’s information can be accessed by applications efficiently.

Advanced topics and High Tech experiments demand for lot of infrastructure. There are areas in living sciences and other subjects where the magnitude of information is so huge that it is more convenient to do the experiment by simulation using computers. The present work relates to development of computer based learning resource that can be used as an online teaching aid or an offline tool to study the Brownian motion in two dimensions. It is an interactive tool where the learner can change the parameters of interest to study the Brownian motion and actually see the effect by way of simulated graphics. Quantitative values of the parameters arising from the simulation study are also available to the learner. The Brownian motion is a phenomenon occurring at microscopic scale and thus actual study of the experiment requires real time monitoring of microscopic development and progress of the Brownian motion which is a tedious task and very difficult to implement in laboratory. To this effect, to carry out the experiment under different desired conditions, a computer based tool is developed that enables the learner to conduct experiment using simulation and see the results quantitatively. It is being uploaded on internet as an online e-learning material.

Abstract—Mobility Management (MM) is one of the major issues of Mobile networks that should be taken into account for providing Quality of Service (QoS) and to meet the subscribers demand (satisfaction). Mobility management techniques are divided into two types (i) Location Management (LM) and (ii) Handoff Management (HM). The LM is used for tracking where the subscribers are locate, and based on that permitting calls, Short Message Service (SMS) and other mobile phone services are delivered to them with the assistance of Intelligent Agent Decision Making Protocol (IADMP). The Redundant Update Remove Algorithm (RURA) which is used for reducing the updation between BSC and MSC. Enhanced Temporal Updation (ETU) reduces the location updates between Mobile Node (MN) and MSC using IADMP. To provide ubiquitous communication for subscribers without any break in the communication, HM protocols play main role in Mobile Networks. In HM process there are four protocols, (i) Double Threshold Protocol (DTP) (ii) Better Base Station Selection Protocol (BBSSP) using Relative Signal Strength (RSS) (iii) IADMP and (iv) Hybrid Decision Making Protocol (HDMP) are used. The Performances of these protocols are analysed. The HDMP and ETU provide QoS in Mobile Networks.

Abstract - This research paper is about data mining (DM) and visualization methods using independent component analysis and self organizing map for gaining insight into multidimensional data. A new method is presented for an interactive visualization of cluster structures in a self-organizing Map. By using a contraction model, the regular grid of selforganizing map visualization is smoothly changed toward a presentation that shows better the proximities in the data space. A Novel Visual Data Mining method is proposed for investigating the reliability of estimates resulting from a Stochastic independent component analysis (ICA) algorithm. There are two algorithms presented in this paper that can be used in a general context. Fast ICA for independent binary sources is described. The model resembles the ordinary ICA model but the summation is replaced by the Boolean Operator OR and the multiplication by AND. A heuristic method for estimating the binary mixing matrix is also proposed. Furthermore, the differences on the results when using different objective function in the FastICA estimation algorithm is also discussed.

Abstract - In a broad sense, an agent is any program that acts on behalf of a (human) user. A mobile agent then is a program which represents a user in a computer network, and is capable of migrating autonomously from node to node, to perform some computation on behalf of the user. In computer science, a mobile agent is a composition of computer software and data which is able to migrate (move) from one computer to another autonomously and continue its execution on the destination computer. Mobile Agent, namely, is a type of software agent, with the feature of autonomy, social ability, learning, and most important, mobility. Mobile agent is an agent that migrates from machine to machine in a heterogeneous network at times of its own choosing. An agent is “an independent software program which runs on behalf of a network user”. A mobile agent is a program which, once it is launched by a user, can travel from node to node autonomously, and can continue to function even if the user is disconnected from the network. Examples can be Personal assistant (mail filter, scheduling), Information agent (tactical picture agent), E-commerce agent (stock trader, bidder) and Recommendation agent (Firefly, Amazon.com).
