摘要: 从分析问题节点引起的路由感染问题出发,探讨了使用基站来鉴别、搜索和隔离问题节点的新思路,介绍了一种隔离问题节点的传感器网络可信体系结构,提出了服务于该体系结构的可信路由协议,该协议通过规避问题节点来选择不包括问题节点的安全路径。仿真实验显示,该方案能有效地提高传感器网络有效发包率并延长网络生命期,减少路由感染影响。该方案适用于以数据为中心的资源受限的传感器网络。

Abstract: Route infection motivates the novel concept of trouble nodes address that are identified, probed and isolated by the sink(s), and a trusted architecture is proposed based on isolation of trouble nodes for sensor networks. A trust routing protocol is introduced for the architecture, which selects trusted paths without any trouble nodes by avoiding trouble nodes and routing around them efficiently using modified geographic routing. Simulations show how the scheme effectively increases the good throughput and energy-efficiency of a sensor network and alleviates the influence of route infection. The scheme is easily used in the data-centric model in energy-constrained sensor network.

Key words: sensor networks, trust architecture, trouble node, route infection
