A Reliable Collaborative Detection Scheme of Event-region in Wireless Sensor networks

Event detection is among the most important applications of wireless sensor networks(WSN). Due to the fact that sensor readings do not always represent the true attribute values, Aiming at the problem of low service quality in WSN, a reliable collaborative distributed detection scheme is presented. This algorithm exploits the spatial correlations among sensor nodes, rather than passing large quantities of raw data through the network, our network instead sends the coefficients of a regression polynomial, aggregation the median information, and judges the final state of the event-region. Simulation results demonstrate the superiority of the proposed scheme in the event-region detection.
