A Secure Adaptive Routing Strategy Using Immune Mechanism in MANET

Many protocols have been proposed to increase efficiency and security of traditional protocols in Mobile ad-hoc networks (MANET), but they are all facing the problem of computation overhead which leads to impracticability. Adaptive routing strategy (ARS) is a novel routing strategy that switches routing protocol according to the network condition. Though this method alleviates the problem of efficiency, it doesn't cover the secure issues. We integrate our security mechanism based on Artificial immune system (AIS), with adaptive routing strategy to enhance efficiency and security. First we presented a more appropriate definition to the measurement of network condition, then we designed a secure adaptive routing strategy based on the definition. At last, we gave a performance analysis to validate the correctness and reliability of our scheme.
