无线传感器网络的自组织可靠性研究

Research on Self-Organization Reliability of Wireless Sensor Network

在大量研究关于复杂网络鲁棒性和容错性等理论的基础上,针对网络自身失效和外界有针对性攻击两种情况,对各种情况的无线传感器网络拓扑结构进行了分析,得到了优化的网络自组织模型,并提出了传感器网络的修正路由算法。仿真结果表明,该算法使得传感器网络的生存能力大幅度提高。

Based on in-depth study of robustness theory of complex network, aiming on the two situations： deficiency of WSN nodes and under external attack, this paper analyzes the error tolerance ability of different topologies of WSN, obtains optimized self-organized topological models of WSN and proposes a refined routing algorithm based on WSN. Simulation results indicate that such algorithm can increase the survivability of WSN under different sorts of failures remarkably.
