SNAuth-SPMAODV with SIP to secure application and network layer in Mobile adhoc network for Military Scenario

A mobile ad-hoc network (MANET) is a wireless network where nodes can communicate with each other without infrastructure. Due to this nature of MANET, some malicious and selfish nodes that try compromise the routing protocol functionality and makes MANET vulnerable to Denial of Service attack in military communication environments. This paper considers military scenarios and evaluates the performance of security-enhanced-Multicast 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) with Session Initiation Protocol (SIP) provides application layer and network layer security and authenticates the neighbor is robust against Denial of Service attack.The SNAuth-SPMAODV protocol has been implemented and simulated on Qualnet 5.0.The performance metrics used to evaluate the proposed method such as packet delivery ratio, end to end delay, throughput, routing overhead and jitter.
