摘　　要：提出了一种基于移动Mesh网络的定位系统,利用Mesh节点作为"锚"节点,建立相对坐标系,移动终端通过测量与"锚"节点之间距离,并通过TDOA定位算法获得自身相对位置信息。对移动Mesh网络定位系统可行性问题进行探讨,主要对移动Mesh网络条件下实现终端定位的性能进行了探讨,并对定位误差进行了必要的仿真验证。仿真结果表明该系统定位精度较高,可实现基于移动Mesh通信网络的终端定位功能。A location system based on mobile mesh communication network is introduced in this paper, the coordinate system is set up by using mesh node as ＂anchors＂ node,and the mobile terminal can obtain its location by measuring the distance to mesh nodes and computing its location using TDOA location algorithm. The feasibility of mobile mesh network location system is discussed, and the location capability of the mobile terminal in the location system is discussed in detail. Moreover, the error of location system is simulated and validated. The result indicates that this system has higher location accuracy, and can realize terminal location function based on mobile mesh communication network.
