Detecting and Eliminating Black Hole in AODV Routing

Mobile ad hoc networks (MANETs) consist of autonomous mobile nodes which interact with other nodes. Nodes being infrastructure less and lack of central management would lead to simple selfishness or in some cases, maliciousness by black holes. Ad hoc on-demand distance vector (AODV) is one of most popular routing protocols used in MANETs. However, it is vulnerable to black hole nodes. The simulation results show by using individual reputation system, alert on finding a black hole node and exchanging neighbor information messages on meeting a new neighbor will help detecting and eliminating malicious or black hole nodes from the networks.
