| 摘 要： | 传感节点有限的能量使得能耗成为路由算法设计要考虑的首要因素。数据融合可以通过合并冗余数据而有效地节约能耗，本文据此提出了一种基于反向组播树的路由算法，算法通过构造一个组播树形成一个以Sink为根的树，其后节点只需将数据发送到一个树上的节点即可，数据经过融合反向转发到Sink。算法具有较好的节能性，而且延时较小，理论分析和仿真实验也表明算法具有好的性能。

| Abstract: | The limited energy in the sensor of sensor networks makes energy is the most important factor when designing the routing algorithm.And data-fusion can fuse the redundant data and save energy effectively,so in this paper,a new algorithm based on reverse multicast tree is proposed.The new algorithm constructs a mult icast tree rooted sink,then data collected by nodes can be forwarded to any node s in the tree and will be consolidated before sent to sink.Theoretic analysis an d simulation results show that the new algorithm has better performances. |
