摘　　要：为了延长无限传感网的生命周期,提高数据传输的实时性。综合了LEACH和PEGASIS算法的优点,提出了一个新型路由协议算法(Linking of Delamination Based PERASIS and LEACH protocol,LDPBL)。该路由算法采用三层网络结构,从上至下依次为BS层,簇头层,簇内节点层,其中簇头层与簇内节点层依次成链传输数据。节点信息的传递由上往下,节点数据的流向由下往上。仿真实验结果表明,该算法能够继承LEACH与PERASIS的优点,与此同时摒弃两者缺点,在提高网络生命周期以及提高数据实时性方面有良好的效果。An improved scheme is proposed under the consideration of the defect of LEACH and PEGASIS.In that scheme,it could increase the survival time of wireless sensor network and the real-time quality.This scheme consist of three-layer：from top to bottom is BS layer,cluster head layer,inside layer.The cluster layer and inside layer transmit the data by the line which is self-created.The transmission of nodes＇ information is from top to bottom,the stream of the date is from bottom to top.Simulation results show that the algorithm possesses are higher energy usage real-time quality and longer survival time than those of LEACH and PERASIS.
