摘　　要：紫外光自组网可以解决紫外光通信中传输距离短、覆盖范围小的问题,性能良好的路由算法可提高网络性能。基于无线紫外光通信信道传输模型,阐述了单条链路节点收发装置进行捕获、对准和跟踪的过程。研究紫外光自组网按需多径距离矢量路由协议(AOMDV,Ad Hoc on-demand multipath distance vector routing),并利用NS2将其与组播按需距离矢量路由协议(MAODV,multicast Ad Hoc on-demand distance vector)进行仿真对比。结果表明,在移动节点数目相同,节点运动区域较小,节点运动区域固定,移动节点数目较多和节点最大移动速度改变的条件下,AOMDV比MAODV性能较优。Ultraviolet (UV) Ad Hoc network can solve the problem of short transmission distance and small coverage in UV communication. A good performance routing algorithm can improve network performance. Based on the wireless ultraviolet communication channel transmission model,the single link node transceiver device′s processing of acquiring,pointing and tracking is introduced. AOMDV routing protocol is studied for the UV Ad Hoc network,and NS2 is used to compare it with the MAODV routing protocol. The simulation results show that the performance of AOMDV is better than that of MAODV,on condition that the number of mobile nodes is same and larger,the moving area of the node is smaller and fixed,and the maximum moving speed of the node is changed.
