Trust Routing Protocol Framework Based on Behavior Assessment for Wireless Sensor Networks

With the scale of network expanding,nodes are likely to implement the transmission of confidential data or work in potential hostile environments,so we need an efficient routing mechanism to guarantee the security of data trans- mission.In this paper,we study the model based on triist.iind design trust routing protocol framework,in order to curb the impact of attacks on network,such as selective forward- ing,tampering,wormhole,flood,improve the reliability of network and theoretically analyze the additional cost of security frame- work.Trust framework is validated through routing protocol,such as directed diffusion and diffusion tree.Experiments show that the trust routing protocol framework can well defend against various kinds of attacks in sensor network,and substantially improves the reliability of network under a small additional cost.Comparing with common routing protocols,in trust routing protocol framework the arrival rate of data packet is increased 35 percents, and the loss rate of data packet is reduced 20 percent.
