| 摘 要： | 针对LEACH协议中簇头随机选举产生、重新建簇频率过高、单簇头非健壮性的不足，提出改进算法LEACH—GAHS。该算法结合能耗、距离信息，利用遗传算法优化簇头生成，并建立候选簇头集来提高算法的鲁棒性和降低建簇的频率，从而延长了网络生命周期。

| Abstract: | For the defects of LEACH protocol, which contain random selection of cluster head, the high frequency of re-building cluster, and non-robustness of a single cluster head, this article proposes an improved algorithm named LEACH-GAHS. This algorithm combines the information of energy and distance, generates cluster head by Genetic Algo- rithm, establishes the candidate cluster head set to increase robustness and reduce the frequency of building cluster, and so extends the network lifetime. |
