| 摘 要： | 为提高移动自组织网络QoS特性,减小组播的时延,利用群论中的直积方法构建了一个类超立方体拓扑结构,它具有对称性强,直径小的特点,给移动自组织网络结点分配虚拟坐标,使其嵌入到该类超立方体中,并在此基础上提出了一种确定性的组播路由算法.理论分析与实验结果表明,所设计的组播路由算法在端到端时延,网络带宽消耗以及组播数据分发的成功率方面更能适应移动自组织网络的需求,并为大规模的移动自组织网络组播通讯在带宽,时延和负载均衡等优化策略方面提供了解决方案.

| Abstract: | In order to improve QoS of mobile ad hoc network and reduce multicast delay,a hypercube-like topology based on direct product method in group theory has been presented,this topology is symmetry and has small diameter.Based on the created hypercube-like topoloy,every node in mobile ad hoc network has been given a virtual coordinate and embedded into the built hypercube-like topology.Based on this model,a deterministic multicast routing algorithm has been proposed.Theoretical analysis and experimental results show that,the multicast routing can adapt the mobile ad hoc network scalability requirements in bandwidth,latency and multcast distribution success rate,and provide a solution for large-scale mobile ad hoc network. |
