摘要：In wireless sensor network (WSN), many low cost sensor nodes are deployed over a geographically limited area without well-established infrastructure. They accomplish the task together. Malicious sensor nodes are well disguised in sensor nodes, so they can attack the whole network using the natural cooperation of WSN. In order to detect malicious nodes and enhance the security of network, this paper presents a novel multivalued trust routing protocol, called MTR, which is based on the concept of sensor's trust and level in topology structure of network. Protocol MTR employs sensor's trust and the number of hops from sensor nodes to Base Station (BS) to ensure the stability of the net. The simulation results show that protocol MTR significantly improves the reliability data transmission to BS and the time to live in the present of compromise nodes. © 2013 IEEE.
