| 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。本文综合了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。节点的操作从上往下，节点数据的流向从下往上。仿真实验结果表明，该算法能过继承LEACH与PERASIS的优点，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。 |

| Abstract:An improved scheme is proposed under the consideration of the defect of LEACH and PEGASIS in this paper. 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 connects inside layer by the line. The operation of the node is from top to bottom, the stream of the date is from bottom to top. Simulation results show that this algorithm possesses higher energy usage real-time quality and longer survival time than those of LEACH. |
