摘要
在已有的LEACH的协议上,提出了一种具有改进型LEACH差异化的路由算法,通过增加阀值和合理调正通信半径,从而避免区域出现的不均匀的情况,对于簇首能量的分析,证明这种改变是有效的。在仿真实验中,使用这种改进型的算法可以发现从剩余能量,平均簇首对比,节点死亡轮数上发现比LEACH协议算法具有一定的优越性,它能够从一定程度上减少网络的能量消耗,提高网络的使用利用率,延长网络的有效使用时间。
Based on the existing LEACH protocol, the article presents a kind of improved LEACH differential routing algorithm, by increasing the threshold and the reasonable adjusting communication radius, it avoids the regionally appears uneven situation. For the cluster head energy analysis, this change is proved efficient. In the simulation experiment, the using of this improved algorithm can be found from the respects of residual energy, average cluster head nodes contrast and death round number that it has certain superiority compared with the LEACH protocol algorithm, which in a certain extent, can reduce the network energy consumption, improve the uti- lization rate of network and prolong the effective using time of network.
