| 摘 要： | 在充分研究现有Zigbee技术的基础上,主要分析了Zigbee无线传感器网络定位系统的通信冲突和定位精度.采用组团协议,选择最先接收到场强信号指示的节点为团长,并提出采用RSSI近似度和选择邻居节点数K选取团员的方法.用以避免定位系统通信冲突并增强系统的健壮性,同时提高定位精度.

| Abstract: | This paper analyzes wireless sensor networks based on Zigbee localization system communication conflict and localization accuracy on the basis of the full study of existing Zigbee technology and use group protocol to solve it.We put the node that the first receive strong signal instructions as the head of the group,focus on using the RSSI approximation and the approximate number of nodes K to select members.It can avoid localization system communication conflict and enhances system robustness and improve po... |
