Performance Evaluation of AODV with Self-Cooperative Trust Scheme Using Jellyfish Delay Variance Attack

In applications with low infrastructural elements, a MANET becomes highly vulnerable to security attacks. These attacks can be active or passive in nature. Active attacker including `Black-hole', `Grey-hole' and `Worm-hole' can modify, listen and inject messages in communication channel. Whereas, a passive attacker does not alter the information; but secretly listens to valuable information i.e. spoofing. Jellyfish attack is one of the illustrations of a passive attack. Jellyfish adjusts to all directing and sending protocol particulars. The present work has been implemented on network simulator, NS 2.35. It is a discrete set of terms and protocol settings for network lay-outing and configurations. The present work has taken 2-routing protocols AODV and DSR; on which JFDV attack has been implemented. The impact of varying number of jellyfish attacker nodes 1, 3, 6 and 9 has been compared in both the protocols. AODV outperforms DSR protocol for several performance parameters, which include “Throughput” and “E2E Delay” with JFDV detection algorithm. Algorithm provides better identification and removal in AODV protocol.
