PERFORMANCE ANALYSIS OF ROUTING PROTOCOLS IN MANET UNDER MALICIOUS ATTACKS

MANETs routing protocols are vulnerable to various types of security attacks such as selfish nodes, grey-hole and black-hole attacks.  These routing protocols are unprotected and subsequently result in various kinds of malicious mobile nodes being injected into the networks. In this paper, three types of attacks such as selfish, grey-hole and black-hole attacks have been applied to two important MANET routing protocols; Ad-hoc On demand Distance Vector (OADV) and Dynamic Source Routing (DSR) in order to analyse and compare the impact of these attacks on the network performance based on throughput, average delay, packet loss and consumption of energy.
