In this paper, we propose a scheme to minimize power consumption and guarantee delay requirement in wireless sensor networks. Based on queue and delay information, we propose a joint controller, which controls both sleeping time and queue threshold in a distributed manner. Also, we provide a delay notification mechanism which helps nodes determine an appropriate queue threshold according to the application-specific delay requirements. We analyze the adaptive behavior of the proposed method using the first-moment approximation. Based on control theory, we derive conditions for system stability. Asymptotic analysis shows that our proposed algorithm guarantees end-to-end delay requirement by controlling parameters of local nodes. Simulation results indicate that the proposed scheme outperforms existing scheduling protocols in terms of delay and power consumption.
