Wireless sensor networks (Wireless sensor networks) is determined by a large number of resource-constrained sensor nodes, formed by self-organized network with specific application background. With modern microelectronic technology, wireless communication technology and the rapid development of network technology, wireless sensor networks have become the most important information and access to one of the most basic skills, widely used in various fields. However, due to their own operating environment constraints, sensor network applications face mobility, interference, and failure-prone and other tests. Therefore, a good network management system is to protect the wireless sensor network stable, reliable, and efficient operation of the important conditions. Wireless sensor network management is a lot of important interrelated factors, such as network traffic, network topologies and communication protocols, etc. These factors make network management for wireless sensor networks is more complex than traditional networks. Firstly, in-depth study and analysis of the existing wireless sensor network management architecture and its typical applications, including centralized, distributed and hierarchical. Second, the energy from the network management effectiveness, stability and scalability and other factors into consideration, for wireless sensor networks lightweight SNMP (Lightweight Wireless sensor networks Simple Network Management Protocol, LW-SNMP), detailed description of its network model, packet format, management structures and MIB design. Then LW-SNMP based on the design and build a lightweight hierarchical wireless sensor network management system (Lightweight Hierarchical Wireless sensor networks Management System, LHWMS), including server management subsystem, subsystem and agency cluster node agent subsystem . Then, given the specific design of the system, function modules and key mechanism implementation. Subsequently, in the next generation of Internet connectivity Beijing Jiaotong University, National Engineering Laboratory equipment independently developed miniature sensing router MSR6680 successfully achieved LHWMS, and the size of the room under a small network performance testing and analysis. Experimental results show that this thesis LHWMS designed to meet the needs of wireless sensor networks, as well as stability, memory effectiveness, scalability, and integration of legacy networks and has great advantages. Finally, the paper summarizes the work done, and the next step suggestions for improvements.
