基于树的Adhoc组播路由协议的研究与改进

移动Adhoc网络以其组网灵活、快捷、不需要预设网络基础设施以及完全分布式等特点，在军用和紧急救援等特殊环境的应用前景非常广阔。在移动Adhoc网络领域，由于节点的带宽和能源非常有限，组播数据传送的重要性日益突出，组播路由技术的研究逐渐成为Adhoc网络的核心研究方向。在基于树的组播路由协议MAODV的基础之上，提出一种简化组播树合并，扩展组播结构路由维护过程的改进方案，仿真实验结果表明改进后的协议提高了分组投递率、降低了时延，是一种比MAODV协议适应性更强的可行性方案。

Research and Improvement of Tree-besed Ad Hoc Multicast Routing Protocol

Because of the network flexibility,efficiency,without the network infrastructure and fully distributed,Ad hoc network has very broad application prospects in military and emergency relief in special circumstances.In the research of Mobile Ad hoc network,as the bandwidth and energy are very limited.The importance of multicast data transmission has increasingly become prominent,and the research of multicast routing technology of Ad hoc network has gradually become the core research direction.In this paper,bas...
