一种基于主观逻辑的无线传感器网络可信路由算法

A Trustful Routing Algorithm Based on Subjective Logic for Wireless Sensor Networks

无线传感器网络中高敏感度数据传输业务要求路由协议设计时必须考虑能量与安全约束.LEACH分簇路由算法没有考虑节点与所选路径的安全性,文中提出的基于主观逻辑的可信LEACH路由算法(TLEACH_BSL)充分考虑节点可信度评价,对改进前后路由算法作了理论性分析及仿真实验比较,为可信路由算法体系的研究提供了思路.

It is needed to consider the energy and security constraint in the proceeding of designing routing protocol of the highly sensitive data transmission of wireless sensor networks. There is no consideration about the safety of nodes and chosen route in LEACH clustering routing algorithm, the trustful LEACH routing algorithm based on the subjective logic （TLEACH_BSL） in this article makes full consideration in node confidence level appraisal and can guarantee the safe transmission of the information. Furthermore this article makes theoretical analysis and simulation experiment comparisons between the two improving and improved routing algorithms and provides the ideas for the research of the trustful routing algorithm system.
