A power conservation technique is one of the essential solutions for sensor networks, which are for the most part not able to refresh their own power source. A sleep or active time control method is an effective power conserving solution because of its ability, in tracking applications, to turn off the radio of nodes that are not involved in packet transmission. However, most current research neglects the importance of QoS. In this paper, we present a sleep-time control mechanism based on a two-tier grid structure: communication grid and wakeup and sleep grid. The hybrid grid structure allows power conservation as well as preservation of QoS. Additionally, we present a framework for a mobile event tacking system, which consists of three phases: grid construction, surveillance, and tracking. The simulation result shows that the proposed method almost guarantees QoS while conserving a significant amount of energy.
