摘要: 探讨了Ad Hoc网络中能量优化的多播路由问题.在一次多播会话中节点功率不变的假设前提下,分析了NJT(Node-Join-Tree)算法,针对NJT算法所生成的多播树中可能存在冗余发送节点的问题,提出了一种新的能量优化多播路由算法——RMT(Refine-Multicast-Tree)算法,给出了RMT算法的复杂性分析,并设计了RMT算法的分布式实现方案.RMT算法在已有多播树中进行本地搜索,寻找是否存在冗余的发送节点,若存在冗余发送节点则将其从多播树发送节点集合中删除,重构多播树,从而达到减少多播树能量消耗的目的,生成能量更优的多播树.仿真实验表明RMT算法性能优于NJT算法.Abstract: The energy efficient multicasting was discussed. Based on the assumption that each node in the network has a fixed level of transmission power during a multicast session, node-join-tree(NJT) algorithm was analyzed. In order to solve the problem that there may be redundant transmitting nodes in multicast tree resulted from NJT algorithm, a new energy efficient algorithm—refine-multicast-tree(RMT) algorithm was proposed. The complexity analysis and distributed implementation of RMT algorithm were also presented. RMT algorithm locally searched existing multicast tree to find whether there are redundant transmitting nodes in tree. When redundant transmitting nodes exist in multicast tree, RMT algorithm deletes such nodes from transmitting node set and reconstruct multicasting tree. The total energy cost of multicast tree was decreased accordingly and thus a more energy efficient multicast tree was generated. Simulation result shows that RMT algorithm performances well compared with NJT algorithm.
