Effect of power avaricious attack on MANET routing protocols

Many routing protocols for Mobile Ad Hoc Networks have been proposed. The efficient routing protocol provides the significant benefits to such networks in terms of both performance and reliability. However, the nature of ad hoc networks makes them vulnerable to attacks especially in the routing protocols. How to protect an ad hoc routing protocol and which protocol works efficiently under the security attacks is an important research topic. This paper focuses on the performance investigation of a reactive protocol i.e. AODV and a proactive protocol i.e. OLSR under a passive attack called selfishness attack. In this work, it is analyzed that under the selfishness attack the proactive protocols outperforms the reactive protocols.
