1. DiSTRO: Distributed 3D Object Design,
Intel Visual Computing Institute, Saarland University, Germany
Role: Early Stage Researcher
Duration: January 2018 – December 2018
Tool: MATLAB, OpenCV
Description: The goal of this project to provide a virtual institute for the research and development of tools for the casual and distributed capture, editing, computational design and fabrication of objects, linking the real and digital worlds. As a research in this project, the task is to use multi-view encoding to generate and process 5D light field data captured with a camera array.
2. Rate Adaptive Multi-Rate Multicast Video Streaming over OpenFlow Networks,
Telecommunications Lab, Saarland University, Germany
Role: Researcher
Duration: June 2014 – December 2017
Tool: Floodlight Controller, OpenVSwitch
Description: Software Defined Network techniques allow network components to process the message transmitted over the network. The proposed method in this project explores SDN feature to improve the quality of the video communication in multirate multicast scenario. A resource efficient multicast tree construction algorithm was developed to stream the video over SDN based networks. The proposed algorithm considers availability of the network resources to construct the multicast path from server to a group of receivers.
3. Scalable Medical Video Transmission over Wireless Networks for Telemedicine Applications,
Dept. of Computer Applications, MIT, Manipal
Role: Researcher
Duration: January 2014 – December 2015
Tool: Exata Emulation Software
Description: In telemedicine applications, the transmission of medical video over wireless channels need to have very high diagnostic end-to-end quality. The medical video needs to be coded using the scalable encoder to make it adaptable to any type of network dynamics. During bandwidth narrowing, diagnostically important region needs to be handled by providing high priority to those regions rather than losing diagnostically important region. Each region of interest (ROI) must be prioritized and these ROI’s can be varied along with better error resilient techniques during transmission order.
4. Video Streaming over Heterogeneous Network,
Manipal Institute of Technology, Manipal
Role: Researcher
Duration: September 2010 – March 2012
Simulation Tool: NS-2
Description: Video communication is gaining interest in the Internet. The heterogenous network technology, and devices involved in the communication make it challenge to provide better Quality of Service. In this research work, we analysed the performance of video communication over different conditions. Also, analysed the influence of layered coding techniques on quality of communication.
5. Intervehicular distance calculation using relative speed,
Dept. of Information and Communication Technology, MIT, Manipal
Role: Co-Principal Investigators
Duration: June 2010 – August 2010
Simulation Tool: NS-2
Description: The VANETs use GPS navigation system to get the position information of the vehicle. But the GPS error leads false position of the vehicle. The vehicle uses the digital map to locate itself and its neighboring vehicle. In this project, a technique is proposed to calculate Intervehicular distance using relative speed. The relative speed gives more trust worthy Intervehicular distance than using GPS.
6. DBR using Location servers for VANETs,
Dept. of Information and Communication Technology, MIT, Manipal
Role: Co-Principal Investigators
Duration: February 2010 – May 2010
Simulation Tool: NS-2
Description: The DBR using Location Service is developed to overcome the shortfalls of DBR. The Location servers are made use for the location the destination vehicles. Here the source vehicle which has data to transmit requests the Location Server for destination vehicle position information. The LS replies with the current location of destination vehicle. Here the number of broadcast packets on the network is reduced due to LS. The delivery ratio is also increased remarkably.
7. Distance Based Routing protocol for VANETs,
Dept. of Information and Communication Technology, MIT, Manipal
Role: Co-Principal Investigators
Duration: August 2009 – January 2010
Simulation Tool: NS-2
Description: The proposed algorithm adopts both, position based and map-based routing technique. In DBR, a connectivity graph based on the duration of connectivity between neighboring vehicles, the Intervehicular distance and the information from the digital map are collectively used to route the data. The neighboring vehicle’s information pertaining to the position of the vehicle and velocity are exchanged and hence updated only when there is a change. This routing technique supports highly dynamic topology of VANET.
