Design And Implementation Of Network Mangement System In Wireless Sensor Network Based On The Software Defined Technology

As the basis for the Internet of things,the development of the wireless sensor network has been received attention.Wireless sensor network is pervasive throughout daily life not only in daily production operations,but also in environmental monitoring.In different occasions,the wireless sensor network plays the role of information transmission and supervision of the Internet of Things.However,with the rapid development of Internet of things,vehicle networking,smart city and other related fields,higher requirements on the traditional wireless sensor network are put forward.The traditional network architecture has been difficult to meet the needs of the communication efficiency of the large amount of data and compatibility requirements according to the different application service.In order to solve the problems existing in the traditional sensor network,we introduced the concept of software defined network,adopting the idea of centralized control to realize the separation of data plane and control plane.Because the wireless sensor network faces the challenges of limited energy,dynamic topology and deployment environment,a perfect wireless sensor network management system is the foundation for ensuring the reliable,efficient and safe running of the network.Based on the existing research of the wireless sensor network and combined with the traditional wireless sensor network management system,we design a wireless sensor network management system technology to achieve effective management of the network based on software defined network.In this paper,we design a management system of wireless sensor network based on softeare defined network to achieve flexible management.Then we describe the management style,management framework and management entity,and introduce the design and implementation of the platform management and local management in the management framework in detail,and proposes a graph layout algorithm to improve the efficiency of the force guidance algorithm based on the initial optimization of the optimization graph.Finally,we use 20 sensor nodes to constitute the software defined wireless sensor network,and we have tested and validated the system,meanwhile,we summarize the research achievements and the next work.
