A Hybrid Approach for Dynamic Intrusion Detection, Enhancement of Performance and Security in MANET

Mobile ad hoc networking (MANET) has been most popular research area for last decade. In MANET node (mobile node) is communicate with each other over wireless link where all nodes behave like both as host and router. In comparison with wired networks, mobile network is more vulnerable to security threat because of no centralized administration. One of the momentous routing protocols used in MANET is AODV (Ad hoc On demand Distance Vector) protocol. The Ad hoc On demand Distance Vector (AODV) protocol is compromised with its security by a various types of attacks due to malicious nodes present in the network. A hybrid approach is given for intrusion detection by removing malicious nodes during the route discovery process. The proposed approach increases the network performance in terms of PDR, throughput and end to end delay and security also.
