Abstract

In many applications of WSNs, the events occur infrequently but once they occur, the corresponding information needs to be sent to the sink node in a short period of time for the necessary reactions. Detection of rare events in a fast and energy-efficient manner is an important issue in WSNs. In this paper, based on the optimal solution for the Best-choice Problem with Bounded Random Observation Number, we propose an Energy-efficient Online Decision Scheme (EODS) to handle this problem. Combining with the design of nodes' duty cycle, the EODS avoids the redundant transmissions and achieves the tradeoff between delay and energy efficiency. Simulation results reveal that the EODS achieves a good balance between delay and energy efficiency.
