Quantitative Trustworthy Evaluation Scheme for Trust Routing Scheme in Wireless Sensor Networks

With the rapid development and application of wireless sensor network(WSN),security and trust are important to the network. The initial requirement for wireless sensor networks is power efficiency. As the cooperation character of the network, trust routing and management are also important to wireless sensor network. As the threats come from various attacks, novel trust routing scheme is proposed to enhance security of the network. Trust routing scheme is becoming a key method to protect the security of protocol in wireless sensor network. Quantitative trust evaluation scheme is proposed to enhance security and reliability of wireless sensor network. The definition and mathematic description of trust routing is proposed in the paper. Ad hoc On-Demand Distance Vector (AODV) routing protocol is used to validate trust routing scheme in wireless sensor network, Route Reply (RREP) Message is extended to record node residual energy evaluation and attack behaviour evaluation. NS-2 simulator is used to simulate the trust routing scheme under different network attack behaviors. Five kinds of node attack behaviors are used to evaluate and validate the trust routing scheme. Simulation results show that trust routing scheme can improve the security and performance of network. It shows better than other security scheme.
