Energy-saving Algorithm Based on Grid Clustering for WSN

无线传感器网络中,能量消耗问题一直最受人们关注。为了节省网络能量,针对现有算法存在的冗余节点过多以及能量利用率较低等问题,在以往算法的基础上,提出了一种基于网格分簇的节能算法,即基于网格分簇的无线传感器网络节能算法EABGC(Energy-saving Algorithm Based on Grid Clustering)。该算法采用虚拟网格和贪婪算法等来节约网络能量。通过仿真实验,该算法与LEACH协议相比,能减少网络的能量消耗,从而达到节能的目的。EABGC算法,能有效地降低网络消耗,实现节能效果。

In wireless sensor network, people most concern the energy consumption. In order to save the energy of network, in view of the existing problems of many redundant nodes and lower energy efficiency, on the basis of previous algorithm, a energy-saving algorithm based on grid clustering, which is a energy-saving algorithm based on grid clustering for wireless sensor network is put forward. The algorithm uses virtual grids and greedy algorithm to save the network energy. Through the simulation test, the algorithm is compared with LEACH protocol, and can reduce the network energy consumption so as to achieve the purpose of saving energy. EABGC algorithm can effectively reduce the network consumption, and achieve the effect of energy-saving.
