Hierachical heterogeneous wireless sensor network management system

We design a multi-functional management system for hierarchical heterogeneous wireless sensor network, including configuration management, performance management and fault management. This system is compatible with SNMP. The MIB (Management Information Base) is extended according to the features of heterogeneous wireless sensor network, so that it can support custom configuration for wireless nodes. Using the cross-layer technology, the information of the lower layer (the MAC and the network layer) and network topology can be collected; Adopting professional graphic interface component TWaver Java to display network topology, supporting both circular layout and spring layout network topology displaying mode, as well as real time switching between two type of network topology displaying mode, then the network topology can be dispersedly and clearly displayed on the screen; In addition, an adaptive fault detection algorithm, AFD, is proposed. This system can be used in daily maintenance and management of the heterogeneous wireless sensor network, also can be used for performance evaluation of network system.
