Network Coding with MGM based Anycast Packet Transmission in Vehicular Ad-Hoc Networks

Mobile Ad-hoc Network routing protocols such as AODV, DSR etc. fail in scenario in which no contemporaneous path exists between source and destination because they try to find end-toend path before data transmission which is not exist in VANET which increase delivery delay and decrease delivery ratio. So VANET uses ‘store-carry-forward’ paradigm. In network coding, source node or intermediate node allows to combine number of packets it has received or generated into one or several outgoing packets. Reliability is one of the issue in network coding. So we use network coding with multi generation mixing in which packets are grouped into generations and generations are grouped into mixing set. We propose Anycast routing protocol for VANET which uses ‘Network coding with multi generation mixing’ to improve the performace. By using simulation we compared the performance of proposed protocol in terms of delay, delivery ratio and throughput with the same protocol using network coding and using conventional scheme. Simulation results suggest, our protocol achieves significantly less delay, higher delivery ratio and higher throughput compared to network coding based scheme and conventional scheme.
