The cooperation among sensor nodes is a significant issue in large-scale, complicated Wireless Sensor Networks(WSN). Target tracking is a canonical application of WSN. The dynamic coalition mechanism in WSN for target detection is an important method to improve the tracking quality which saves much energy. An energy efficient coalition formation algorithm is needed because the energy resource of WSN...
Fault detection of wireless sensor networks has been studied intensively in recent years under the assumption that manager nodes are default probe stations. However, some additional fault detection tasks will make so busy the manager node to be failed more quickly. Moreover, at the first beginning period most sensor networks are working normally without any dead nodes and the probing work are actually...
The modern society has come to rely heavily on IT services. To improve the quality of IT services it is important to quickly and accurately detect and diagnose their faults which are usually detected as disruption of a set of dependent logical services affected by the failed IT resources. The task, depending on observed symptoms and knowledge about IT services, is always disturbed by noises and dynamic...
