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 an unmanned and uncontrollable environment. In addition to many threats such as information leakage, information tampering, replay attacks and denial of services that wireless networks face, wireless sensor networks also face sensor nodes Easily manipulated by attackers, and access to all the information stored in the sensor node, in order to control part of the network threat. By studying the cooperation in ant colony system, the trust cooperation mechanism based on BTRM is applied to wireless sensor network. This paper analyzes the current research status of common trust cooperation model, induces several common trust models, and proposes the function and architecture of the trust cooperation simulation system based on BTRM for wireless sensor networks. This paper focuses on the design and implementation of wireless sensor trust cooperation theory and trust cooperation simulation system based on BTRM model. By applying the trust cooperation mechanism in BTRM to WSN environment, the simulation shows that this mechanism has the advantage in the output average path length, average satisfaction , The average satisfactory deviation and so on have greatly improved.
