近年来,随着研究领域的广泛、技术的深入,无线传感器网络具有良好的应用前景。无线传感器网络在实际应用过程中十分容易受到故障的干扰,从而严重影响其工作的效率和质量。传感器节点是随机部署在各种特殊区域的,人类很多情况下无法亲自对其设备性能进行维护。因此,针对传感器网络故障的诊断技术有别与传统有线网络,针对无线传感器网络故障诊断技术的研究有一定的现实价值。
In recent years, with the extensive research field and the deepening of technology, the wireless sensor network has a good application prospect. Wireless sensor networks in the actual application process is very susceptible to interference, which seriously affect the efficiency and quality of their work. Sensor nodes are randomly deployed in a variety of special areas, in many cases humans can not personally maintain their equipment performance. Therefore, there are some practical values for the research on the fault diagnosis technology of sensor network, which is different from the traditional wired network and the research on the fault diagnosis technology of wireless sensor network.
