对于无线网络的节能需求,本文从两个方向来谈论节能方案。第一个方向是提高数据通信成功率,减少重传次数以节省能量。该点主要是讨论了分簇算法中簇头选举时综合考虑其剩余能量和通信成功率,以选择出能量较多、通信成功率较高的节点作为簇头。第二个方向是通过减少节点工作时间,以使其更多时间进入休眠节能状态。对于如何减少工作时间谈论了两点:一是加入精确时间同步机制,以最大限度的保持节点的低能耗休眠时间;二是优化时隙资源使用方案,减少无谓空等工作时间。最终的验证结果显示出了良好的节能效果。

In oder to save the energy of node in wireless network, this paper puts forward two proposals from two aspects. The first proposal is to improve the success rate of data communication and reduce the number of retransmissions to save energy. What is mainly discussed in the first proposal is that when selecting cluster head in the clustering algorithm, this paper synthetically consider the residual energy and success rate of communication of node to select the node which has more residual energy and higher success rate of communication as the cluster head. The second proposal is to reduce the work time of the node and make it have more time to sleep to save the energy of the node. Considering how to reduce the working time of node, this paper solves this problem from two aspects: the first is by the precise time synchronization mechanism to maximize sleep time of node; the second is to optimize the use of timeslots to reduce unnecessary waiting time. Finally, this paper proves that these proposals above have good effect in saving energy.
