摘要
提出的基于分区的移动组播算法旨在解决移动节点远离本地网络且持续快速运动情况下的组播重构开销过大的问题,通过将网络划分成不同的区域并指定一个区域代表,降低了组播树重构频率。仿真结果表明,此算法较之FHSR算法在网络利用率及组播重构开销方面有更好的性能。
The R, egion-based Mobile Multicast algorithm proposed in this paper aims to solve the problem of oversize multicast reconstruction cost when mobile nodes move away from home network at high speed. The proposed algorithm reduces multicast reconstruction frequency by dividing the network into different regions and specifying a regional representative. The simulation result shows that the proposed algorithm performances better than FHSR algorithm in terms of network utilization and muiticast reconstruction cost.
