Preventing black hole attack in MANETs Using Randomized Multipath Routing Algorithm
Sherril Sophie, Maria Vincent, W. Thamba Meshach · 2012
Abstract — Mobile ad hoc networks are infrastructure less network where the nodes themselves are responsible for routing the packets. The dynamic topology of MANETs allows the nodes to join and leave the network at any point of time. Wireless ad hoc networks are not protected against the attack of malicious nodes, because of security vulnerabilities in the routing protocols. One of the attacks most common in MANETs is the Black hole Attack. In the new scheme a channel aware feature is added on the AOMDV Protocol to overcome the channel fading. However this scheme does not provide any security against the Black hole Attack. This paper contributes a mechanism that generates random multipath route which is circumventing black holes. The security and energy performance are analytically investigated. Extensive simulations are performed to verify and validate the mechanism.
