Multipath Routing in VANET: Multi-Agent based Approach

Abstract

In VANET routing of data is a exciting task owing to the high dynamics involved in this network. Delivery of data to the projected destination turns out to be very puzzling. Single path routing suffers from drawbacks like unreliability and etc. To manage such situation multipath data delivery is very nominal. In multipath routing more than one path discovered between source and destination node. Data packet can be sent simultaneously in all paths or data packet can be send by selecting path one after another. It is up to the routing algorithm to select path thoughtfully to deliver data proficiently. However existing multipath routing protocols even though compute multipath, only one path will be engaged in actual communication at any given time. Hence this work proposes Multipath Routing in VANET: Multi-agent based Approach which calculates multiple paths amongst source and destination. Further, all such computed paths will be employed for information dissemination. NS2 simulation of the proposed approach in realistic mobility models show that it can select more stable link and improve the network performance.
