Impact of malicious node on broadcast schemes

Abstract

Broadcast is frequently used operation in vehicular adhoc network (VANETs) for sharing traffic, weather, and safety information among vehicles. Relevance based approach forward high priority traffic for information sharing and removes the redundant and surplus messages. The relevance based approach depends upon the intermediate nodes and consider ideal scenario where there is no selfish and malicious node but it is not possible in real life scenario. We in this paper simulate the relevance based approach using NS-2 in a real scenario and consider the impact of malicious node and determine how much throughput of network is affected by malicious node. © 2009 Springer-Verlag Berlin Heidelberg.
