摘要


The wireless sensor network is often deployed in harsh and unattended environment and is easily attacked and interfered due to its vulnerability. Most of routing protocols for wireless sensor network were initially designed for saving energy and had less consideration on security. In view of this, a secure routing protocol based on reputation mechanism is proposed. Firstly, considering at the problems of trust mechanism including complex computation of trust value and excessive energy consumption, a binomial distribution reputation mechanism (BDRM) is presented. On this basis, aiming at the deficiency of cur- rent routing protocol in security defense, a secure routing protocol ST-GEAR is designed. This protocol has a better ability to defend against attacks by introducing the secure bootstrap model and the BDRM in the routing. The simulation results show that the ST-GEAR routing can improve the transmission rate of packet and reduce the loss rate of packet and energy consumption.
