Research And Design Of The Management System In Wireless Sensor Network

Along with the development of wireless communication, large scale integrated circuit and embedded technology, the wireless sensor network takes a rapid development. Recently, the research based on wireless sensor network focus mainly on routing protocol, energy consumption and data processing, etc. And wireless sensor network application is very extensive, and has been used in intelligent transportation, the intelligent building and intelligent logistics system, and so on. As the applications are based on wireless sensor network, the network data acquisition and wireless sensor network management system are needed.Wireless sensor network is an energy limited network, resource nodes is extremely valuable, and directly related to the performance of the network life and application. So development based on the wireless sensor network is different from the development based on traditional network and software, that is a new development area, so for application developers, they have to give a great deal of effort on sensor network management, that is a time-consuming.Wireless sensor network management system uses the dedicated management protocol to transport data, to collect, analyze and store the node and network performance and fault information. Management systems use management platform as a management center, and set local agent on node to execution node management, collection node and performance information, to monitor local and neighbors node fault, and promptly report to the information.To satisfy the requirement of wireless sensor network, the node identifier should be allocated automatically, and sensor network transmission within the reliable indispensable. This paper proposes th algorithm that will assign the tasks of identifier allocation to the cluster nodes in wireless sensor network, and the cluster head node is responsible for the task of identifier allocation in the cluster. As the requirements of network management, this paper designs the network management protocols, defines the message format and news content, and solves the transmission of management messages in wireless sensor network management.Finally the simulation of network management tests the functions and management procedure, and analyses the results. At last, this thesis summarized the research work, and prospects the next job.
