摘要: 无线传感网络的节点部署随机性很强,每个节点的利用率不同,经常用到的节点可能会能量耗尽死亡,传统的网络协议将传感网络随机分为不同的簇,簇头能量很微弱的节点可能仍被选为簇头,造成了节点死亡,其没有避绕死亡节点的机制,造成通讯稿效率不高.为此提出微粒群优化LEACH的无线传感网络通信优化方法,结合LEACH的优点,簇头选择时使用微粒群的高度智能优化的特点将簇头当前能量与原始能量作为选择因素构造目标函数.通过适应度值避让节点中的死亡节点.实验仿真结果证明,簇头微粒群优化后传感网络能量损耗大大降低,死亡节点通信数目也变小.提高了通讯效率.Abstract: Research Optimization communication of Wireless sensor network.Wireless sensor network structure is complex and has many levels.This paper puts forward a Wireless sensor network communication optimization method based on Particle swarm optimization LEACH.Using particle swarm optimization of high intelligencecan avoid death node.The experiment results show that the improved algorithm can improve the Communication efficiency
