一种移动Ad Hoc网络多播路由协议

A Multicast Protocol for Mobile Ad-hoc Network

提出了一种基于分割树的移动Ad Hoc网络(MANET)多播路由协议(TPBOM).该协议中,信源基于成员节点的定位信息创建一个Steiner树覆盖图.为满足可扩展多播群的要求,信源再利用最大权反向分割(MHRTP)的树分割算法将其分割为若干个区,并将每个区封装进一个树分发数据包中,以便将所创建的Steiner树分发至所有成员节点.封装的数据包中不包含目的地址列表,数据则沿该Steiner树进行传输.仿真结果表明,TPBOM在可扩展的多播群中获得了较高的性能.

In this paper,we propose a multicast protocol named Tree Partition-Based Overlay Multicast（TPBOM）for MANET.In TPBOM,the source creates a Steiner tree based on the gathered location information of all member nodes.Then the source utilizes Maximum Height Reverse Tree Partition（MHRTP）mechanism to part the Steiner tree into several zones and encapsulates each zone into a Tree Distribution Packet（TDP）including no destination list in order to distribute the Steiner tree to all member nodes.Data packets are sent forward along the Steiner tree. Simulation results show TPBOM achieves high performance in scalable multicast group.
