Detection of Sybil Attack for P2P Security in MANETs

Abstract

A MANET is an infrastructure-less type networks, which consists of the number of mobile nodes with wireless network interfaces Sybil attack is a serious threat for today’s wireless adhoc networks. In this attack a single node pretends several other nodes using various malicious means.  Here we considered Topology based routing protocols like DSDV and DSR for the detection of SYBIL attacks in P2P system. Performance metrics such as packet delivery fraction, throughput, and end-to-end delay are evaluated using NS-2.

Keywords – Mobile Ad-hoc networks, Sybil attack, NS 2.
