摘要： 针对传感器网络的节点定位问题提出一种使用3个普通信标节点定位全网的基于RSSI的圆环重叠(ROBRSSI)定位机制.通过误差转换、未知节点与其二跳邻居间协作设计,有效抑制已有研究中RSSI测量误差的影响,降低未知节点与信标节点间相对位置要求,实现未知节点的有效定位.基于ROBRSSI定位机制,研究了传感器网络中新加入节点的定位.仿真实验验证了算法的有效性.

Abstract: For the localization of nodes in WSN, a new sensor localization approach based on ROBRSSI(ring overlapping based on received signal strength indicator) using three beacons was presented. Designing the handling of error transforming and the collaboration between unknown nodes and their two-hop neighbors, the effect of measurement error of RSSI on localization accuracy as shown in earlier works is restrained efficiently with the requirement for the relative position between node and beacons reduced to implement the node's precise localization. Then, the localization of new comers in WSN is studied on the basis of ROBRSSI. Simulation results showed the validity and superiority of the algorithm.
