高效率的小规模Ad Hoc组播路由协议

摘要

Ad Hoc网络中,组播路由协议具有广泛的应用前景.但由于网络拓扑的变化和节点能量的限制,设计具有高效传输能力的组播路由协议比较困难.通过综合比较表驱动路由协议与按需路由协议的优缺点,并且考虑Ad Hoc网络中节点的移动性以及路由发现与路由维护的方法对传输效率的影响,在无状态组播路由的基础上,使用表驱动与按需路由驱动相结合的路由方法,提出一种新的组播路由协议,使传输效率有较高的提升.%The multicast routing protocol has a wide application in Ad Hoc network. It is hard to design a multicast routing protocol with high efficient and transmission capability for the change of topology. On considering the mobility, discovery and maintenance of routing in Ad Hoc network, a new efficient routing protocol based on the stateless multicast routing protocol is proposed to improve the transmission efficiency.
