D.devi Aruna, P.subashini . SNAuth-SPMAODV: Secure Neighbor Authentication Strict Priority Multipath AODV against Denial of Service attack for MANET in Military Scenario. International Journal of Computer Applications. 48, 4 ( June 2012), 1-6. DOI=10.5120/7333-9047
A mobile ad-hoc network (MANET) is a peer-to-peer wireless network where nodes can communicate with each other without infrastructure. Due to this nature of MANET; it is possible that there could be some malicious and selfish nodes that try to compromise the routing protocol functionality and makes MANET vulnerable to Denial of Service attack in military communication environments. This paper consider military scenarios and evaluate the performance of Security-enhanced-Multipath AODV (Ad hoc On-demand Distance Vector Routing) routing protocol called SNAuth-SPMAODV (Secure Neighbor Authentication Strict Priority Multipath Ad hoc On-demand Distance Vector Routing). The protocol discovers multiple paths between sender and receiver nodes without introducing extra packets into the network and authenticates the neighbor offering robustness in a secured MANET. The SNAuth-SPMAODV protocol has been implemented and simulated on Qualnet 5. 0. Based on the simulation result, it can be shown that SNAuth-SPMAODV does provide a more reliable data transfer compared to the normal AODV if there are malicious nodes in the MANET.
