Mixed synchronous and asynchronous duty-cycling protocol in sensor networks

Wireless Sensor Networks are usually relying on the energy source to the battery, so lifetime of the sensor nodes is limited. Duty Cycling is known as one of the methods to reduce the energy consumption of wireless sensor networks. Therefore, efficient Duty Cycling needs to be performed to extend the lifetime of the network. In this proposed method, efficient Duty Cycling is performed while securing scalability by using a synchronous protocol and an asynchronous protocol in combination. We compare with the existing methods and show that network lifetime is extended.
