摘　　要：组播是指单个发送者对应多个接收者的一种网络通信,在组播技术中,通过向多个接收方传送单信息流方式,可以减少具有多个接收方同时收听或查看相同资源情况下的网络通信流量。为了有效地利用MANET的有限资源,组播在移动自组网中扮演着越来越重要的角色。由于移动自组网中终端设备依赖于的电池供电,为了延长节点的工作时间,要求尽量减少节点的能量消耗,从而延长整个网络的使用寿命。该文对当前存在的基于能量优化的组播路由算法进行了分析和比较,阐述了目前亟待解决的主要问题和今后的研究方向。Multicast is the communication between a single sender and multiple receivers on a network.Multicast technologies are used to reduce network traffic when there are many receivers that want to listen to or view the same source simultaneously by delivering a single stream of information to hundreds of recipients.To use effectively limited resources in MANET(Mobile Ad Hoc Network),multicast plays a more and more important role.Because power supplies nodes in MANET depend on the batteries,it calls for efficient use of their batteries for extending nodes and networks lifetime.The problems about routing algorithms for energy-efficient multicasting in MANET are deeply discussed,and some routing mechanisms are analyzed and compared.It points out the direction to the research in the future.
