摘　　要：针对现存定位机制中定位误差大或有较高的硬件要求问题和无线传感器网络低成本、低功耗的特点,在TDOA技术的基础上,提出了一种用于无线传感器网络的基于距离的节点自定位算法.该算法采用限制测距信号的跳数和重复运行的方式,使定位更精确,减少网络流量和负载.For the existing large localization error or higher hardware requirements and wireless sensor networks of low-cost, low-power requirements, a new wireless sensor networks range-based self-positioning algorithm was proposed based on the basis of TDOA technology. By limitation of the hop counts of the distance signal and repeat runing mode, the algorithm can make more precise positioning, and reduce the network traffic and load.
