摘　　要：针对无线传感器网络的能量受限和网络寿命有限的问题,结合梯度和数据流机制,对经典的LEACH分簇路由协议中簇头的选举及簇内通信方式进行了改进.Matlab的仿真结果表明,改进后的基于梯度与数据流机制的分簇路由协议与LEACH协议相比,能更为有效地节约节点能量,使网络寿命延长约50%～65%.In consideration of the limited energy and limited life in wireless sensor network, the election of cluster heads and the communication way within the cluster in the classic LEACH routing protocol are improved based on the grads and data flow mechanism. The Matlab simulation results show that, compared with LEACH, the improved protocol--Cluster Routing Protocol based on grads and data flow mechanism can be more effectively in saving the energy of the nodes, the network life could be prolonged about 50% - 65%.
