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。
In this paper, we study a split tree-based Mobile Ad Hoc Network (MANET) multicast routing protocol (TPBOM). In this protocol, the source creates a Steiner tree coverage map based on the location information of member nodes. To meet the requirement of scalability, , The source divides it into a number of zones using the tree partitioning algorithm with maximum-weight reverse partitioning (MHRTP), and encapsulates each zone into a tree distribution packet in order to distribute the created Steiner tree to all member nodes , The encapsulated packet does not contain the destination address list, and the data is transmitted along the Steiner tree. The simulation shows that TPBOM achieves high performance in the scalable multicast group.
