摘　　要：当前,分布式无线传感器网络(DWSN)已得到广泛应用并服务于许多领域,而其网络架构和节点仍存在一些技术及性能优化难点,影响应用效果。软件定义网络(SDN)是具有控制转发分离思想可编程化功能的新型网络架构,其能对节点设备和层间协议进行软件定义虚拟化。为了提升DWSN的关键技术及性能优化的安全性和可操作性,降低网络复杂性,在DWSN中引入SDN框架形成新的基于SDN的分布式无线传感器网络(SDDWSN)框架。首先,从引入SDN必要性入手探讨了SDDWSN框架要点;其次,重点从网络通信、资源处理和控制管理等方面研究了SDDWSN框架的相关技术和性能优化;最后,设计案例对其安全性和事件可操作性方面进行定性对比分析,研究结果体现出了SDDWSN的优势。At present,distributed wireless sensor network(DWSN)has been widely used and served in many fields,but there are still some technical and performance optimization difficulties in its network architecture and nodes,which affect the application effect.Software defined network(SDN)is a new network architecture with the programmable function of controlling and forwarding separation.It can virtualize the software definition of node devices and interlayer protocols.In order to improve the security and operability of DWSN’s key technologies and performance optimitation,and reduce the network complexity,the SDN framework is introduced into the DWSN to form a new SDN-based distributed wireless sensor network(SDDWSN)framework.Firstly,the main points of SDDWSN framework are discussed by introducing SDN necessity.Secondly,the related technology and performance optimization of SDDWSN framework are studied from the aspects of network communication,resource processing and control management.Finally,the advantages of SDDWSN are reflected by designing cases and qualitatively comparing and analyzing their security and event maneuverability.
