An Efficient Anonymous Routing Protocol for Mobile Ad Hoc Networks

Providing anonymous routing in mobile ad hoc networks (MANET) has been a hot issue for the purpose of security and privacy concerns. But there are very few have been done about providing a valid method to detect malicious node and providing a trustworthy protection over whole network. In this paper, we introduce a localized trust management which can primarily remove malicious nodes, and propose an efficient anonymous routing protocol by node that participates in the protocol encrypts entire message with trust key and says Hello to its ancestor within expiration time. It makes malicious node can be detected and isolated from the network. In this way, a anonymous and secure route path can be established in a hostile environment. Meanwhile, it is able to efficiently against the Denial-of-Service (DoS) attack.
