摘　　要：在移动分组无线网环境中,多播路由协议起着非常重要的作用。由于MPRN受到节点移动和带宽的限制,已有多播路由协议的可靠性不高。文章提出基于Gossip的传输协议(GBTP),旨在提高多播路由协议的数据分组递交率。在MFGRP上进行了GBTP的模拟和性能分析,研究了GBTP对分组递交成功率的影响。仿真实验显示GBTP协议可以有效地提高MFGRP协议的分组递交率。Multicast protocol plays an important role in MPRN environment.However,MPRN functions under severe constraints such as mobility of nodes and bandwidth restriction of the wireless medium.These restrictions make the existing multicast routing protocols very unreliable even in moderately sized networks.This paper proposes gossip-based transport protocol(GBTP)to improve packet delivery of multicast routing.GBTP is implemented over MFGRP without much overhead and its performance is studied.Simulations show that the packet delivery of MFGRP is significantly improved and the variation in number of packets delivered is decreased.
