摘要： 从平衡节点能量消耗的角度出发,考虑无线广播的特性,提出了一种新的节约能量的组播路由协议。基本原理是,利用Wireselthier等提出的最小增量的思想,考虑不同节点能量消耗的不平衡,提出一种节约能量的multicast树构造算法,在使网络的总能量消耗减小的条件下实现节点能量消耗的分布平衡。协议通过区域预测机制来维护multicast树。

Abstract: This paper introduces a new multicast routing protocol that exploits the broadcast nature of the wireless communication environmentand addresses the need for energy-efficient operation. On the construction of energy-efficient multicast tree,a node joins the multicast tree by takinginto consideration not only the incremental cost but also the energy consumption of it. This protocol uses a localized prediction scheme for treemaintenance. It provides a scheme to balance the energy consumption among all nodes.
