无线传感器网络通常部署在无人维护、不可控制的环境中,除了具有一般无线网络所面临的信息泄露、信息篡改、重放攻击、拒绝服务等多种威胁外,无线传感器网络还面临传感节点容易被攻击者物理操纵,并获取存储在传感节点中的所有信息,从而控制部分网络的威胁.通过研究蚁群系统中的协作,把基于生物激励信任模型(BTRM)中的信任协作机制应用于无线传感器网络.分析了当前常见的信任协作模型研究现状,归纳出常见的几种信任模型,并提出基于BTRM的无线传感器网路的信任协作模拟系统的功能及体系结构.重点论述了基于BTRM模型的无线传感器信任协作原理和信任协作模拟系统的设计和实现,通过把BTRM中的信任协作机制应用到WSN环境中,模拟显示,该机制在输出平均路径长度、平均满意度、平均满意偏差等方面均有较大的改进.

Wireless sensor networks are usually deployed in the non-controlled environment without maintenance, facing problems of a general disclosure of information, information tampering, replay attacks, denial of service and other threats, and also facing the threat of the mass nodes being easily targeted by physical manipulation, with the information stored in the sensor nodes being taken and used for the manipulators to control a part of the network. Based on the studies of the collaboration of the ant colony system, a trust model based on biologically inspired (BTRM) trust in the cooperation mechanism is proposed for the use in wireless sensor networks. Some trust models of collaboration curently in use are analyzed, and a wireless sensor network based on BTRM collaborative trust simulation software features and software architecture is proposed. The principles and the implementations of the collaborative trust simulation system are discussed. The simulation shows the output average path length, the average satisfaction, the average deviation, which indicates an improved performance.
