Trust-Aware Secure Routing Protocol for Wireless Sensor Networks

Abstract

In order to improve the security and energy saving efficiency of wireless sensor networks, a Trust-aware wireless Sensor network secure Routing Protocol(TSRP) is proposed.Based on the new direct trust value, indirect trust value, volatilization factor and residual energy, the node calculates the comprehensive trust value of the neighboring node to evaluate the safety index of the node, and to quickly identify and eliminate malicious nodes that cause black hole attacks, selective forwarding attacks, Hello Flood attacks, and sinkhole attacks.As for covert wormhole attacks, the sink calculates the optimal path based on the link quality, transmission distance, and hop count of multiple links to ensure that the selected route is safe and energy efficient.The simulation results show that compared with AODV and TBSRP protocols, the optimal route selected by TSRP can effectively reduce the load of each node, and reduce the network delay and packet loss rate.
