SAODV: A MANET Routing Protocol that can Withstand Black Hole Attack

Ad hoc On-demand Distance Vector routing (AODV) is a widely adopted network routing protocol for Mobile Ad hoc Network (MANET). The design of AODV, however, paid little attention to security considerations, hence resulting in the vulnerability of such MANET to the black hole attack. On the basis of AODV, this paper proposes and implements AODV suffering black hole attack - BAODV (Bad Ad Hoc On-demand Distance Vector Routing suffering black hole attack), which can simulate black hole attack to MANET by one of nodes as a malicious one in network. BAODV can be regarded as AODV, which is used in MANET exited black hole attack. Based on BAODV, this paper also proposes a secure and efficient MANET routing protocol, the SAODV protocol, which aims to address the security weakness of the AODV protocol and is capable of withstanding the black hole attack. Experimental analysis shows that the SAODV routing protocol is more secure than the basic AODV.
