| 摘 要： | 针对无线传感器网络的特点,提出了一种新的分簇算法.在选择簇头时,节点根据自己的地理位置与能量决定是否成为簇头,使得簇头在网络中均匀分布;在数据传输阶段根据节点的权重来选择中间节点进行数据传输,减少网络消耗的能量从而延长网络的生存时间.仿真结果表明该算法可以显著延长网络寿命,提高网络的业务容量.

| Abstract: | According to the characteristics of WSN,this paper proposes a new algorithm.A node decides whether to be a cluster head based on its energy and location in the network,so that the cluster heads in the network have a more rational distribution;and the cluster heads choose the mid-nodes according to the weight of nodes in the data transmission.The simulation results indicate that this algorithm can make a remarkable improvement in the life and the capacity of the network. |
