WSN中基于二分法与移动Sink的数据收集协议
Data Collection Protocol for WSN Based on Dichotomy and Mobile Sink
摘要
Abstract
In order to improve the survival period of wireless sensor networks,a data collection protocol for Wireless Sensor Network(WSN)based on dichotomy and mobile Sink called PBDM is proposed.The network is divided into two equal subdomains by the dichotomy,the intersection of two domains is the trajectory of mobile Sink.With the increase of mortality rate of sensors,and the inner subdomain is divided into two equal areas by the dichotomy,which can identify and change the trajectory of the mobile Sink.The entire network is controlled by topology,where static and mobile Sink nodes coexist.Cluster heads collect interests in the cluster and send the data to the nearest Sink with minimum hop counts.Simulation results show that PBDM is better than LEACH in the base station to obtain information,the remaining energy of the network and the number of surviving nodes.It can improve the efficiency of data collection and prolong the lifetime of WSN.关键词
