摘要
文中研究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,为满足可扩展性的要求,信源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,仿真实现表明,TPBOM在可扩展的多播群中获得了较高的性能。
A multicast protocol named tree partition-based overlay multicast （TPBOM） for MANBT is studied. In TPBOM, the source, based on the gathered location information of all member nodes, creates a Steiner tree. Then, for the need of expansibility, this source utilizes maximum height reverse tree partition （MHRTP） mechanism to partition the Steiner tree into several zones and encapsulate each zone into a tree distribution packet （TDP） with no destination, thus to distribute the Steiner tree to all member nodes. Data packets are transmitted along the Steiner tree. Simulation results show that TPBOM could achieve high performance in scalable multicast group.
