A security adaptive protocol suite: Ranked Neighbor Discovery (RND) and Security Adaptive AODV (SA-AODV)

With the increasing demand of mobility and ad hoc networking, vulnerability of wireless networks is also becoming a crucial issue. This dissertation sheds light on the security features of wireless communication, and proposes a model with an increased integration of security features. The proposed model, a Ranked Neighbor Discovery (RND), and a Security Adaptive Ad-Hoc On-Demand Distance Vector (SA-AODV) routing protocol suite lays out the percept of solution for the security issues, which includes the neighbor discovery, as well as the routing protocol for transmission. The neighbor discovery phase consists of the determination of trusted neighbors, based on distance metrics, leading to a process of trust ranking. The routing protocol, using the fact of the trusted neighbors, and the required security level, then sets up a security adapted route from the source to its destination. The main advantage of this protocol pair would be the achievement to obtain a route with a user-defined level of security for a specific application. The two protocols thus provide the anchor to a package for a total solution for a secured environment for wireless transmission with an increased integration of security features.
