%X This paper addresses problems in controlling quality of service (QoS) in wireless sensor networks(WSNs). QoS is defined as the number of awakened sensors in a WSN. Sensor deaths (caused by batteryfailure) and sensor replenishments (caused by redeployment of new sensors) contribute to the difficulty ofcontrolling QoS in WSNs. A previous research developed a QoS control scheme based on the Gur Gamealgorithm. However, this scheme does not consider the energy consumption of sensors, which shortensWSN lifetime. This paper proposes a novel QoS control scheme that periodically swaps active andsleeping sensors to balance power consumption. Ourstudy also uses the distribution manner of theprevious work. Our scheme significantly extends WSNlifetime and maintains desired QoS. Simulationsthat compared our scheme with previous schemes in various environments show that our scheme build arobust and long-lasting sensor network capable of dynamically adjusting active sensors.
