RSRP: A Robust Secure Routing Protocol for Mobile Ad Hoc Networks

Routing scenario in ad hoc networks is different from infrastructure-based wireless networks; since in ad hoc networks each node acts as a router and is responsible for managing topological information and ensuring correct route learning. Although a number of secure routing protocols have been proposed so far, all of them have certain advantages and disadvantages. Hence, security in ad hoc networks is still a contentious area. In this paper we first explore the security problems and attacks in existing routing protocols and then we present the design and analysis of a new secure on-demand routing protocol, called RSRP which confiscates the problems mentioned in the existing protocols. Moreover, unlike Ariadne, RSRP uses a very efficient broadcast authentication mechanism which does not require any clock synchronization and facilitates instant authentication.
