[Abstract]:With the rapid development of microelectronics, sensors, networks and wireless communication, wireless sensor networks, as a key design, have become more and more widely and important in various fields.However, the inherent problems such as special design, difficult to change the behavior strategy after network deployment, and difficult to manage the network function make the research, design and practical application of wireless sensor networks face great challenges.In this paper, an improved sensor network system based on the idea of software definition network and its architecture:: SDN-WSNare proposed, and a comprehensive software solution is provided.Based on the idea of software definition of network, this paper studies the separation of data forwarding and control logic by decomposing the traditional tightly coupled network architecture into three separate architectures of application, control and equipment, and provides centralized information collection.Resource integration, network management and behavior control are innovative systems to address the inherent limitations of wireless sensor networks at this stage.In this paper, the design of each network component in the system is described in detail, and a network reconfiguration algorithm based on SDN-WSN system is proposed.Based on Cooja simulation platform and Contiki operating system, a data classification method based on hash algorithm is introduced in this paper. The design of node software architecture and function module is completed, and the development of protocol stack software is realized.In the research, the server database and the terminal user monitoring center based on the three-tier software architecture are designed and developed, which provides a platform for query display, algorithm processing and analysis of the history and real-time information of the multi-monitoring area in the network.In this paper, an automated network performance benchmarking platform is constructed, which provides an efficient, automatic and standardized network performance benchmark testing method for the system.Through simulation and test, it is proved that SDN-WSN system can improve the programmability, expansibility, configuration and manageability of traditional wireless sensor networks.It provides a new attempt, thinking and complete software solution for the research and application of software definition network in wireless sensor networks.
