Issues for Event Monitoring in Event-Driven Wireless Sensor Networks

This paper gives out a survey on event monitoring in Event-driven wireless sensor networks (EWSNs). In EWSNs, there are mainly two tasks, one is accurate event detection with higher detection probability and lower false-alarm probability. The other is reliable dissemination of the event information after accurate detection. In this paper, we firstly address the design issues for event detection and reliable dissemination, and then some existing detection scheme and dissemination protocols for event information are introduced and compared. Finally, several problems to be solved are outlined.
