TARS: Trusted Adaptive Routing Strategy with Back-Off Observing Mechanism

Mobile ad-hoc networks (MANET) have a wide array of military and commercial applications. Many traditional protocols can not meet various increasing requirements in efficiency and security yet. In this paper, we propose a novel solution in a different perspective. First we present a more appropriate definition to the measurement of network condition, in order to reform a more precise two-dimensional criterion. Second we propose a Back-off Observing Mechanism (BOM) to improve efficiency by considering the network context. Third we take full advantage of trusted computing technology to design a secure scheme, which could protect users against various attacks. Combining all three components, we form Trusted Adaptive Routing Strategy (TARS) with BOM. At last, we give a performance analysis of our scheme, which shows that TARS with BOM outperforms previous work in both efficiency and security, and we experimentally prove this conclusion.
