提高网络整体性能与节能，将加权因子引入到LEACH协议改进方法中，根据每个节点的剩余能量、网络平均剩余能量、节点与网络在前一轮中所消耗的平均能量来确定最优簇头。综合考虑数据信息传输与接收的能耗、簇头节点的能耗以及传输ADV 的能耗优化簇头节点数量。采用M atlab进行仿真对比研究，结果表明，与其它几种协议相比，本协议更能够显著降低节点能耗，网络中的簇头节点达到均匀分布状态，且其生命周期更长。
提高網絡整體性能與節能，將加權因子引入到LEACH協議改進方法中，根據每箇節點的剩餘能量、網絡平均剩餘能量、節點與網絡在前一輪中所消耗的平均能量來確定最優簇頭。綜閤攷慮數據信息傳輸與接收的能耗、簇頭節點的能耗以及傳輸ADV 的能耗優化簇頭節點數量。採用M atlab進行倣真對比研究，結果錶明，與其它幾種協議相比，本協議更能夠顯著降低節點能耗，網絡中的簇頭節點達到均勻分佈狀態，且其生命週期更長。

To improve the properties of network as a whole and save the energy ,the weighting factor is introduced to the LEACH protocol to optimize the cluster head based on the residual energy of every node ,average residual energy of the network and the average consumption of former circle . The optimized numbers of nodes are determined according to the energy consumed during the data transmission , energy consumption of cluster head nodes and ADV transformation energy consumption .Matlab simulation results demonstrate that there are such features such as low energy consumption ,even node distribution and long-life span in the improved protocol ,compared with other protocols .
