摘　　要：利用地理位置信息提供的便利,针对Ad Hoc网络多播协议存在的不足,通过局部范围内构造网状多播树结构、减少链路长度、降低应答请求数目和预测节点移动情况等方面做了进一步优化。还介绍了协议的操作方法、协议格式和数据结构。仿真结果表明该协议有较好的数据传递率和较小的延迟。In this paper, we propose several schemes to optimize the performance of multicast routing protocol in Ad Hoc networks taking advantage of geographic information, through constructing mesh multicast tree structure, reducing links distance, decreasing the number of reply, predicting mobility. In addition the algorithm, frame structure and table structure were presented. The simulations result shows that it can improve success transport ratio and reduce the latency.
