An efficient event detecting protocol in event-driven wireless sensor networks

The most important goal in event-driven wireless sensor networks(EWSNs) is to transmit the event information to users timely. One of the most important factors that would make it possible to reach this goal is the design of efficient detecting protocols. In this paper we present an efficient event detecting protocol(EEDP) designed for event monitoring applications based on geographical routing. In the event area, each node broadcasts its primary detection result to make a decision corporately. And then nodes will choose the nearest node to destination as forwarder to reduce the delivery time. To improve the event detection probability, EEDP makes final decisions combing with other single decisions. EEDP is a highly efficient and accurate protocol for the event detection applications where the constraints of end-to-end delay and reliability are stringent.
