Design and implementation of network management system for large-scale wireless sensor networks

Wireless sensor networks consist of a large number of low-cost and micro sensor nodes, which form the networks in wireless and ad hoc way to achieve the tasks that contain gathering, processing and transferring data in the deployment region. Sensor network management is to monitor and control the operational status of sensor networks, enabling them to provide effective, reliable, safe and economical services. With the increase of WSNs applications. WSNs management has become more and more important. A network management system for large-scale wireless sensor networks (WSNMS) is presented and implemented in this paper, which is designed and implemented with the characteristics of WSNs. The functions which WSNMS has implemented include four categories: configuration management, performance management, fault management and accounting management. According to the results of actual experiments which consist of 215 nodes as managed objects and a gateway, WSNMS is able to undertake the large-scale network management functions and has good performance. ? 2011 IEEE.EI
