| 摘 要： | 通过对LEACH-C等协议的研究及改进,提出一种基于能量估算的集中式分簇路由协议LEACH-EE。在LEACH-EE协议中,基站根据接收到的各个簇的数据量来估算每个簇内节点的能量消耗情况,并根据估算结果来重新确定下一轮的簇首和簇结构。只有在一定条件发生时,或者间隔相当长的时间,才需要传感器节点向基站汇报自己的能量等信息。仿真结果表明,与LEACH、LEACH-C协议相比,LEACH-EE协议更能节省网络能量,延长网络的生命周期。

| Abstract: | Based on the study and improvement of LEACH-C protocol, a centralized clustering routing protocol based on energy estimate （LEACH-EE）is proposed in this paper. In LEACH-EE, the base station estimates energy consumption of each node according to the received data. Then the base station selects cluster heads and cluster structure of the next round according to estimation results. Only when certain events occur or an interval for quite a long time, it is needed that sensor nodes send information about their energy or position to base station. The simulation results show that, compared with LEACH and LEACH-C, LEACH-EE can save more network energy and prolong the network life cycle. |
