无线传感器网络已经成为下一代无线通讯的重要方式,快速诊断和定位故障节点是保障网络正常工作的一个重要需求.设计一种新型的故障诊断和定位算法,此算法通过引入基于容错定位集的坐标系统来提高诊断准确率并且降低了故障诊断和定位过程中的通信代价.理论分析和仿真实验验证了此算法的性能优越性.
Wireless sensor network (WSN) has become an important way for the next generation of wireless communication. To quickly diagnose and locate the faulty nodes is an important requirement to ensure the normal operation of the network.A new fault diagnosis and location algorithm is designed.This algorithm introduces the coordinates System to improve the diagnostic accuracy and reduce the communication costs in the fault diagnosis and positioning process.The theoretical analysis and simulation experiments verify the performance advantages of this algorithm.
