摘要 LEACH-AH算法是通过对网络节点坐标的分析设置节点的象限参数,并计算了不同层次圆环区域的半径r_i,设置节点的环域参数值h,实现了网络节点的象限分割与圆环区域化。仿真验证证明:LEACH-AH算法通过限定每轮簇头节点的广播地理范围,限制无线传感器网络终端节点与簇头之间数据发送、接收的传输距离,对促进网络中簇头节点的负载平衡、提高网络的能量效率,具有较为明显的效果。 LEACH-AH is an improved algorithm based on LEACH.That set parameters of nodes by analysing its coordinates and calculating radius of annular domain to regionalize the network nodes.By simulation,LEACH-AH limited broadcasting distance of cluster head and regionalized between terminal node and cluster head for data transmission.It promoted load balancing,and improved the energy efficiency of the Wireless sensor network,with more obvious effect.
