提出一种基于生命期划分的节能数据传输策略。利用能耗判定建立多层簇,并在保证能耗均衡的基础上划分节点生命期,同时利用节点工作状态轮转,进一步延长了网络生存时问。仿真结果表明,本方法相比于其他一些能量有效的网络协议,拥有更长的网络生存时间及更均衡的网络能耗。
An energy-saving data transmission scheme based on life period division was proposed. Multi-layer cluster was constructed on the basis of energy consuming prediction and the life periods of sensor nodes were divided to ensure the balance of energy consumption. By changing node's working mode, network lifetime was further extended. Simulation results show that this method provides longer lifetime and better equalizes energy consumption than some other energy-efficiency network protocols.
