Information Table based Decision Approach for Broadcast Storm Suppression in Vehicular Ad-Hoc Networks

Abstract

Various multi-hop applications in MANETs in general and VANETS in particular, use broadcasting as a method for propagating useful traffic information, paging a particular host, route discovery etc. to neighboring nodes located within a logical and geographical boundary. However broadcasting via the conventional mechanism leads to high level of network contention, and flooding at Data Link Layer which causes dropping of packets and loss of information. In VANETs the network topology is dynamically changing and selfarranging and a minor loss of packet or end to end delay may propagate in time and evolve in a chaotic scenario in real time use case. In this paper we have presented a novel routing algorithm -MARS. MARS is based on i-table approach analogous to IP-Table model as decision control mechanism in deciding the next hop node for packet forwarding. It mitigates BSP, specifically in VANET applications and scenario as we have considered the properties of VANET in our use case. A comparison of results with existing routing protocols viz. AODV and EIGRP for the defined performance metrics against that obtained with MARS in EXata Simulation environment has been shown.
