无线MANET是一类无任何基础设施和中央管理机制、拓扑可动态变化的移动自组织网络,可适用于某些特定的应用环境.QoS路由、多播及移动性管理已成为这类网络的一类重要研究课题,尤其是QoS多播路由是其中需要解决的重点关键问题.文中提出一种移动adhoc网络QoS多播路由协议(QMRP),它可为移动网络环境提供QoS敏感路由.在QMRP中,各局部节点只需维护局部多播路由信息和搜集其他簇的相关信息,而无需维护adhoc全局网络状态.QMRP允许多播组成员动态加入/退出多播组,且支持多维QoS约束.描述了QMRP和实现路由决策的主要过程及其正确性证明与复杂性分析,并通过仿真测试了该协议的性能,验证了其有效性和可用性.
Wireless MANET is a type of mobile self-organizing network with any infrastructure and central management mechanism that can dynamically change its topology and is suitable for some specific application environments.QoS routing, multicasting and mobility management have become one of such networks Important research topics, especially QoS multicast routing is one of the key issues to be solved.This paper proposes a mobile ad hoc network QoS multicast routing protocol (QMRP), which can provide QoS-sensitive routing for mobile network environment.In QMRP , Each local node only needs to maintain local multicast routing information and collect information about other clusters without maintaining the adhoc global network status.QMRP allows multicast group members to join / leave multicast groups dynamically and support multi-dimensional QoS constraints. QMRP, the main process of routing decision making and the verification and complexity analysis of its correctness. The performance of this protocol is tested by simulation and its validity and availability are verified.
