摘要
Ultra-Wideband(UWB)技术被认为是最适合进行室内无线定位的技术,非常适合用于无线传感网中,但是由于无线传感网络的特殊性,例如无组织性、低功耗性、节点多,所以无法直接将传统的UWB定位技术应用到无线传感网中。提出了一种在无线传感网中基于令牌环的多节点协同定位协议,在该协议中没有参考基站,任何节点的关系都是对等的。该协议可以使用较少的测距帧(请求帧与应答帧合二为一)让每个节点均获得与所有其他节点的距离,进而实现相对定位。
Ultra-Wideband （UWB） technology is considered to be the most suitable for indoor wireless location and is very suited for wireless sensor networks （WSN）. However, due to the special nature of wireless sensor networks, such as unorganized, low power consumption and multi-node, so the traditional UWB location technologies cannot be directly applied to WSN. A multi-node co-location protocol based-on Token Ring is presented in WSN, where there is no reference base station and any nodes are peers. This protocol uses less ranging frames （request and answer in one frame）, makes each node get the distance to the others and then determine the relative position of each node.
