Abstract :
Energy conservation is a primary concern in sensor networks. Several MAC protocols have been proposed to address this concern. However, the tradeoff between power consumption and latency has not been thoroughly studied. In this paper, we propose a sensor medium access control protocol with dynamic duty cycle, DSMAC, which achieves a good tradeoff between the two performance metrics without incurring much overhead. Moreover, DSMAC is able to adjust its duty cycle with varying traffic conditions without assuming any prior knowledge of application requirements. Both analytical and simulation results have been presented in this paper.
