[摘要]：The most important goal in event-driven wireless sensor networks is to transmit the event information to users as soon as possible. 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) specified for event monitoring applications. In the event occuring area, each node broadcasts its primary detection result to make a decision corporately. And then the decision-made node will choose the next hop using the underlying routing protocol to forward a single alarm packet. To improve the reliable transmission of the single alarm packet, we use a dynamic multicopy scheme similar as conventional multipath routing for continuous flow. The simulation results validate that EEDP is a practical and efficient protocol for event detection applications where the constraints of end-to-end delay and reliability are stringent. |
