移动自组织网络（MANET）是一种分布式无线网络。自由移动、自配置、快速部署等特点使得MANET适用于各种任务。组播可以有效地支持各种应用和服务。 MANET中现有的大多数组播路由协议仅考虑组播组中的一个源，当协议扩展到多源组播时，其效率变得低下。在本文中，我们提出了一种基于共享树的多源组播路由协议（STMRP），以在多源组播环境中提供高效的组播。所提出的共享转发树和多路径路由保留了多播效率和鲁棒性。仿真结果表明，该协议在多源组播环境下保持了投递率，且不损失组播效率。
A mobile ad hoc network(MANET) is a distributed wireless network. The characteristics such as free mobility, self configuration, and fast deployment make MANETs suitable for various tasks. Multicasting can efficiently support a variety of applications and services. Most of the existing multicast routing protocols in MANETs consider only one source in a multicast group and become inefficient when the protocol is extended to multi-source multicasting. In this paper, we propose a shared-tree-based multi-source multicast routing protocol (STMRP) to provide efficient multicasting in the multi-source multicast environment. The proposed shared forwarding tree and multi-path routing preserve multicast efficiency as well as robustness. Simulation results show that the proposed protocol maintains the delivery ratio without losing multicast efficiency in the multi-source multicast environment.
