Abstract: The Gur Game algorithm is introduced in LEACH to control the total number of active nodes for wireless sensor networks.Thus some nodes are sleeping in order to save their energy,at the same time the number of cluster head will be reduced when the algorithm meets the requirement of its node density in high density wireless sensor networks.Simulation results show that the improved algorithm can prolong the lifetime of the system,comparing with the original LEACH.

摘要: 在LEACH中引入了Gur Game算法,来实现对无线传感网络中工作节点总数的控制。在节点密度较高的网络中,当算法满足它的节点密度要求时,允许部分节点进入低能耗状态同时也减少了簇头节点个数。仿真实验证明改进算法与LEACH相比能有效延长了系统的生存时间。
