摘要: 针对现有信任感知路由协议中信任模型较为简单且能耗优化不足的问题,提出了一种基于信任与能耗均衡的安全分簇路由协议(SCR-TBE).采用模糊综合评判模型并引入多种评判因素计算直接信任,根据偏离度对推荐信任进行过滤与权重分配,并在计算综合信任时考虑历史信任.同时设计簇头惩罚系数,加快恶意簇头的识别与隔离的速度.通过划分监控区域进行非均匀分簇,缓解能量空洞现象.将节点信任值、剩余能量以及数据传输距离作为路由选择因素.设计入簇函数与转发函数,降低恶意节点参与数据传输的几率.仿真结果表明,所提协议与LEACH-C协议和TLES协议相比,数据包数目与能耗均衡性均得到较大提高,提升了无线传感器网络的安全性与可靠性.

Abstract: Aiming at the problems that the trust model is simple and the energy consumption is not optimized enough in the existing trust-aware routing protocols. A secure clustering routing protocol based on trust and balancing energy consumption (SCR-TBE) is proposed. Introducing multiple evaluation factors, direct trust is calculated by fuzzy comprehensive evaluation model, and the recommendation trust is filtered and weighted allocation based on the deviation degree, and comprehensive trust is calculated added historical trust value. And the cluster head penalty coefficient is designed to speed up the identification and isolation of malicious cluster heads. By dividing the monitoring area, the unequal clustering is achieved to alleviate the energy hole phenomenon. The node trust value, dump energy and data transmission distance are chosen as routing factors. The cluster function and forwarding function are designed to reduce the chance of malicious nodes participating in data transmission. Simulation results show that, compared with LEACH-C and TLES protocols, both the number of data packets and the energy consumption balance have been greatly improved, enhancing the security and reliability of wireless sensor networks.

Key words: wireless sensor networks, trust evaluation, secure routing, balancing energy consumption
