摘　　要：节点选择是保证无线传感器网络满足系统QoS需求的最重要问题之一,一种性能较好的节点选择机制可以在保证数据精度的前提下延长网络生命周期。针对WSN节点选择问题进行了描述及分类,着重研究了几类当前具有代表性的节点选择机制,并分析比较了各自的性能及缺点;最后对节点选择的进一步研究方向进行了展望。Sensor selection is one of the most critical problems of guaranteeing the desired QoS （ quality of service） require- ment in wireless sensor networks. A kind of sensor selection schema with better performance can prolong the network lifetime as long as possible on the premise of high-precision data can be measured. This paper covered the description and classification of sensor selection schemes. At the same time, it explicitly studied the recent representative sensor selection schemes, and ana- lyzed their characteristics, then it presented and compared performance and disadvantages. At last, put forward the several research directions for future.
