摘　　要：为了给无线"日盲"紫外光网格网中的接入层和路由层提供更多接入节点的坐标信息,以获得高质量高效率的无线通信效果,采用"三边测量"定位算法在无线"日盲"紫外光网格网中进行节点坐标定位计算,得到了适用于紫外光传输信道下的计算公式,并对此算法进行了仿真。结果表明,当选择合适的收发仰角时,定位误差能够低于0.01km。对于对准精度要求并不苛刻的非视距紫外光通信而言,此算法是可行的。In order to provide more position information of the accessed nodes to media access layer and routing layer in a wireless＂ solar-blind＂ ultraviolet mesh network, trilateration position algorithm was employed to locate the nodes in the wireless network and function for the ultraviolet channel was found. Finally, this algorithm was simulated. The simulation showed that when appropriate transmitting angle and receiving angle are selected and the position error could be less than O. 01kin. This algorithm is feasible for the ultraviolet communication which does not need rigorous pointing accuracy.
