Secure On-demand Routing Protocol for Ad Hoc Network

The security issue of the ad hoc network has attracted the attention of people.Therefore,the security of the routing protocol for the ad hoc network is the key problem.A secure ad hoc on-demand routing(SAOR)protocol suitable for ad hoc network is proposed,which uses the session key between pairs of mobile nodes and message anthentication code based on hash function to verify the validity of the route discovery and route replies.By binding the MAC address with ID of every node,the various complex attacks such as wormhole attacks are defended by the proposed neighbor-node maintenance mechanism.NS-2 simulation results show that SAOR can effectively detect and thwart most of attacks upon MANETs(mobile ad hoc network).
