The nodes in Wireless Sensor Networks (WSNs) are usually powered by batteries with finite capacity and one design challenge in sensor networks is to save limited energy resources to prolong the network lifetime. Moreover, the definition of Quality of Service (QoS) and the metrics to evaluate the performance of a wireless sensor network are different from traditional networks. There are different Metrics for quality of service in wireless sensor networks and most of them are application-dependent. One of the most important of them is the number of active nodes. Regarding the sensors redundancy, we can improve the network lifetime by activating enough number of nodes and making the others sleep. Also, proposing a method that uses the nodes energy equally can prolong the network lifetime. In this paper, we propose an energy efficient scheduling method called Energy Signal Scheduling (ESS). Then, we present QoS-aware Energy Signal Scheduling (QoS-ESS). The QoS-ESS method improves ESS by dividing the sensor network to some clusters and applying the ESS for each cluster separately. The effectiveness of the proposed method is evaluated using NS2 simulator. We have simulated our proposed method and compared its functionality to some other methods. Simulation results show high efficiency of the proposed method.
