中文摘要: 无线传感器网络中节点由容量有限的电池进行供电,在实际应用中给电池充电往往不可行。如何在保证通信质量的前提下,提高通信效率,节省节点能量消耗,已成为无线传感器网络应用面临的关键问题。针对此问题,本项目以分布式信源编码、分布式压缩感知及网络编码为研究对象,定性、定量分析三种算法编码结构特性,设计复杂度可分级的联合分布式信源网络编码算法和联合分布式压缩感知网络编码算法,探索将该算法模型和实现方法应用于无线传感器网络中,以达到提高网络数据传输效率、节省节点能量消耗的目的。联合分布式信源网络编码算法和联合分布式压缩感知网络编码算法的研究对发展中的无线传感器网络、无线多媒体传感器网络及物联网均具有重要的理论研究意义和应用价值,并可推广到其他的无线通信网络中,推动联合信源网络编码进一步发展。

英文摘要: Nodes in wireless sensor networks(WSNs) are supplied by battery with limit capacity, the charging of which is not available in practical use. How to improve the communications efficiency and reduce energy consumption of the nodes while maitaining the quality of communication is of importance for application of WSNs. In our project, we study distributed source coding(DSC), distributed compressed sensing(DCS) and network coding(NC) to desgin complexity scalable joint DSC-NC and DCS-NC algorithms. The developed algorithms will be used in WSNs to improve the data transmission efficiency and to reduce the energy comsuption of nodes. The research of joint DSC-NC and DCS-NC algorithms will further expand the joint source-network coding theory, which is meaningful for the developing wireless communications networks such as WSNs, wireless multimedia sensor networks(WMSNs), and internet of things (IoT).
