Reliable Distance Vector routing protocol to handle Blackhole and Selfish (RDVBS) nodes in Ad hoc Networks
Sandhya Aneja, Neelima Gupta · INTERNATIONAL JOURNAL OF NEXT-GENERATION COMPUTING · 2012
Properties of Mobile Ad hoc Networks (MANETs) present major vulnerabilities in security. The threats considered in MANETs may be due to maliciousness of a node that intentionally disrupts the network by using variety of attacks and/or due to selfishness of the node which does not perform certain operations due to a wish to save power. None of the existing algorithms to mitigate black hole attacks handles selfish nodes. We present a first such algorithm which handles blacknode attack as well as selfish nodes. A co-operative security scheme called Reliable Ad hoc On-demand Distance Vector routing protocol has been proposed to solve the problem of attack by Blackhole node as well as Selfish behavior (RDVBS) . RDVBS behaves like AODV in the absence of attack with only a slight increase in the routing overhead and, detects and isolates black nodes and selfish nodes in the presence of attack. It also recovers from the attack when a black node leaves the network or a selfish node becomes good. Our protocol is also superior to the previous known algorithms in terms of routing overhead. The protocol also handles multiple and cooperative black nodes.
