一种改进的层次型移动组播协议

摘要

This paper introduces the existing hierarchical mobile multicast protocol -- MobiCast protocol, analyzes the advantages and disadvantages of this agreement.To join by tunnel technology based on MobiCast protocol,and reduce the improved base station cost etc..Simulation and analysis show that,the improved MobiCast protocol has a multicast data packet loss rate is low,network maintenance overhead is small,the handover delay characteristics of the short.%论文介绍了现有层次性移动组播协议——MobiCast协议，分析了该协议的优缺点。在MobiCast协议的基础上通过加入隧道技术，并减轻基站开销等方面进行了改进。仿真与分析表明，改进后的MobiCast协议具有组播数据丢包率低、网络维护开销小、切换延迟短等特点。
