COMIP: Cluster based overlay and fast handoff mobile IP system for video streaming in VANET's

Video is the most recommended media for information dissemination in VANETs (Vehicular Adhoc Networks) as it gives clear and quick understanding of information to the drivers. The real time and on-demand video helps vehicles on road in various possible ways. An improper provider not only leads to frequent interruptions of communications, but the transmission of the invalid video fragments would also result in the waster of precious bandwidth. However, VANETs high mobility characteristics and packet loss during communications blackouts difficult the deployment of video services in vehicular networks To address the issue, a novel video source decision scheme, named COMIP (Cluster based overlay and Fast Handoff Mobile IP System) based video delivery over VANETs, is proposed in this paper. The on-demand clustering approach, nodes with the same video requirement/supply and moving features are clustered to study the deploy ability of a video on demand. It has been analyzed the packet loss produced by network reconfiguration during handoffs and its influence in the video streamed quality. Using Mobile IP without and with fast handoffs we have taken the effects of mobility over the video transmission. We show that although fast handoffs techniques minimize blackouts. The simulation is done using SUMO and NS-2. We have checked the COMIP algorithm with the routing protocols AODV and GPSR protocols in changing topology and high mobility. The quality of service is studied on the basis of end-to-end delay and packet loss ratio. We also simulate the start up delay and Handoff latency by using the above scheme in efficient video streaming in VANETs.
