S-MAC

Wireless sensors have been developed for many different applications such as sensing temperature and humidity of environment or car and even human tracking applications, also, it can be used for military applications. The sensor's devices are either physically placed at their sensing area, or they may be randomly dispersed, as from being dropped from an airplane or helicopter. Because of the main feature of sensors are they built to work as a standalone appliance in hard or inaccessible positions, their energy and power feeding system is one of the critical issues in the field of wireless sensor network challenges. Another important critical issue in the architecture of wireless sensors is topology changes which affect the energy issue, the scalability impact by nodes which leave or join the sensing area of the sensor and how much time nodes in the network need to be fast self-recovered with a certain degree of sensing range coverage for the system. The topology convergence time impact on the latency. As MAC protocol performance which tolerated based on scalability considered as a tradeoff for minimizing both energy consumption and latency with a density of nodes and topology changes, Therefore, the contribution of this research is to answer the following open question:-

How Scalability factors impact on the S-MAC protocol Performance?

The scalability is related to the number of nodes and the area of collecting and sensing, also scalability related to radio range, where energy consumption related to collision and overhearing.

This research will address these important factors together. Typical power consumption levels of different modes, sensing area ranges and number of nodes, also the minimum required operating time will be considered in a simulation tool. The simulation tool trace files will monitor and collect critical data which will be analyzed and necessary in the evaluation of S-MAC as an efficient MAC protocol for wireless sensor network operation.

Study and comparison between two target functions of the RPL protocol in the Internet of Things

The RPL is the standard routing protocol for IoT The general performance of Low Power and Lossy Network LLN is highly dependent on the choice of routing protocol and quality of its implementation because they are very resource-constrained, such as power supply therefore, control traffic, power consumption, and packet delivery ratio plays a vital role in the performance of the routing protocol. Two objective function within RPL protocol ETX and OF0 is used determine route for packets within IoT networks. Nonetheless, the IoT network design and the spread of sensors or devices will have a major impact on which objective function to choose for routing the packets.

Therefore, a comparative study of using (ETX) and (OF0) to prove their effectiveness in reducing energy consumption and delivery of packages using simulator cooja with using a different network topology. The comparison will be based on a number of the objectives that mentioned above and to indicate which of these functions are efficient based on power consumption and packet delivery ratio.

Motivation

I. In order to be able to choose the best RPL protocol, we need to make a broad comparison of the RPL functions in order to be able to design the Internet of Things that allow us to reduce the power loss and the packet loss, and thus a comparison between ETX and OF0 will be done in order to reach the desired goals.

II. To analysis deeply depeformes of to object function and determine which of them satiable for different internet of things Topologies paced on performs matrices which are Energy consummation, packet loss, delay.

This research is aimed to answer the following questions:

1 Which objective function that fits IOT networks in terms of packet loss and power consumption?

2 Which network design is the best fit for both objective function ETX and OF0

Convergence Time Analysis of Border Gateway Protocol Using GNS3

The border gateway protocol (BGP) is the routing protocol used to maintain connectivity between autonomous systems on the Internet. Empirical measurements have shown that there can be considerable delays in BGP convergence after routing changes. The delay affects the performance and the Internet connection Also, some applications are affected by the delay, The delay should be reduced to raise the connection efficiency. One contributing factor in this delay is a BGP-specific timer used to limit the rate at which routing messages are transmitted. We use the GNS3 simulator to explore the relationship between convergence time and the configuration of this timer. For each simple network topology simulated, we observe that there is an optimal value for the rate-limiting timer that minimizes convergence time . This research is aimed to answer the following questions:

§ Which BGP timers and Link failure impact on BGP delay?

we will study different timers of BGP such as keepalive timers, hold timers, route advertisement interval timers, update delay timers and we will change these values to see the convergence of BGP.

In addition, we will analyze different schema of link failure detection such as keepalive Message and bidirectional forwarding detection (BFD).

§ Which network design is the best fit for BGP?

This study will analyze different topology networks such as linear topology and tree topology, we will see the convergence time based on different topologies, we will analyze the BGP delay based on different topologies where we will focus on BGP timers and the impact the number of hops especially in the linear topology because the number of hops is a major cause of delays.
