Performance Analysis of AODV and DSR Routing Protocols of MANET Under Wormhole Attack and a Suggested Trust Based Routing Algorithm for DSR

EasyChair Preprint 1617

Abstract

Mobile adhoc network (MANET) is a network where the nodes can move freely in the network, self-assemble themselves and can interact with each other without any help from any centralized authority or fixed infrastructure. Due to its’ highly dynamic and self-configuring nature MANET is susceptible various types of attacks like blackhole attack, wormhole attack, rushing attack, spoofing attack etc. Here, in this paper the effect of wormhole attack on MANET’s two main reactive routing protocols namely Ad-hoc On Demand Distance Vector (AODV) and Dynamic source Routing (DSR) is analyzed and compared by increasing the number wormhole tunnels in MANET. Here, we will see that DSR is greatly affected by this attack, so, as a solution a trust based routing algorithm for DSR is proposed to prevent the caching of attacked routes.
