Abstract

Target monitoring and event detection are very critical issues in wireless sensor networks. Sensor nodes forward the sensory data to the base station by relaying through intermediate nodes used as relays, from which users collect valuable information. The multi-criteria target monitoring is still important in wireless sensor network application scenarios. In order to support energyefficient monitoring and simplify the complexity of dealing with heterogeneous sensor networks, in this paper, we propose a multi-criteria target monitoring strategy using MinMax operator in formed virtual sensor networks. The strategy builds a hierarchical structure by distributed clustering technique on the network before forming virtual sensor network to meet various monitoring requirements from different kinds of application deployment. Then, for the multicriteria monitoring of virtual sensor networks framework, we present method of setting and updating hierarchical thresholds by using the MinMax operator. Finally, the simulation results demonstrate that the strategy can effectively reduce the energy consumption and increase the system lifetime.
