Abstract:

Mobile Ad Hoc networks are multihop wireless networks which are acentric and self-organizing. Due to the unreliable wireless media, host mobility and  lack of infrastructure in the network, the security of network is a critical problem. The security of routing is critical for the running of the Ad Hoc   network directly. Based on the AODV protocol, we propose a mutual authenticated AODV protocol. With the mutual authentication between network nodes and   the simultaneous exchange of keys in the route discovery of demand routing, the correctness of routing is ensured. Simulation results are given by evalu ating SAODV.

Key words: mobile ad hoc network;network security, secure route
