Data collection method for delay tolerant wireless sensor network by satellite communication
一种结合卫星通信的容迟无线传感网数据收集方法

Under the research background of sparse wireless sensor network deploying in wide area,this paper designed a data collection architecture,and orders were sent to sleeping nodes in destined area by satellite Geocasting.Data Mule collected nodes' data and got back by satellite,and layout the Data Mule's movement path,a convex hull-based algorithm and communication protocol.Simulation results show that this method can solve the data collection problem in sparse wireless sensor network under complex environment...
