报告摘要：In this talk, we will provide an overview on the research and applications of wireless sensor networks. Then we will focus on the continuous data collection problem in wireless sensor networks with a mobile base station by using distributed coding. The coding and decoding schemes for the data collection in wireless sensor networks will be introduced. Some proposed schemes will be presented. The efficiency of the proposed schemes will be shown through comprehensive theoretical analysis and the performance evaluation.
