Secure Anonymous Routing in Trust and Clustered Wireless Ad Hoc Networks

Wireless ad hoc networks , especially in the hostile environment, are vulnerable to traffic analysis which allows the adversary to trace the routing messages and the sensitive data packets. Anonymity mechanism in ad hoc networks is critical securing measure used to mitigate these problems. In this paper, we propose a novel secure anonymous routing scheme for clustered wireless ad hoc networks. In our proposed scheme, we use the bloom filter to establish secure anonymous routing in trust and clustered wireless ad hoc networks. It provides not only the basic sender and receiver anonymity, but also the link anonymity and the identity anonymity to the forwarders en route.
