无线传感器网络是一门新兴的技术，具有广泛的应用领域。而基于接收信号强度指示（RSSI）应用的无线传感器网络，需要对网络中接收到同一个节点的多个RSSI值进行滤波。为了对RSSI滤波有一个全面的认识，介绍了几种滤波方法，详细综述了每种滤波方法的原理和特点，最后指出应根据具体情况，权衡滤波效果、算法复杂度、节点能耗等各方面因素，选择一种或者多种算法混合的滤波方法。

Wireless sensor network is an emerging technology,which has a wide range of applications,but the wireless sen-sor networks based on the received signal strength indicator(RSSI)application need to filter the multi-RSSI values of the same node received by network. In order to have a comprehensive understanding of RSSI filtering,several filtering ways are intro-duced. The principles and characteristics of each filtering method are summarized in detail. Finally,it is pointed out that the fil-tering effect,algorithm complexity,node energy consumption and other factors should be weighed to select a filtering method or a hybrid filtering method mixed with more algorithms.
