Abstract
AbstractBeing enthused by the stringent energy and processing constraints of the Internet of Things (IoT) technology, duty cycle becomes the basic mechanism of energy conservation in IoT networks. Duty Cycle involves the fraction of time to keep the node in sleep and active state. Keeping in view the significance of duty-cycling techniques, several techniques have been emerged from the last few decades. Duty cycling depends upon certain factors such as synchronization of nodes, hardware/software complexities, network area, topology, and latency. Dynamic sensor networks such as IoT do not take into account the topology changes because of the fixed criteria of duty cycling. Therefore, Media Access Control (MAC)-based adaptive duty-cycling techniques are thoroughly discussed in this study. The study laid down the empirical notion for researchers to develop energy-efficient duty-cycling strategies in an IoT system.KeywordsInternet of thingsEnergy-efficiencyDuty cyclingSleep–wake up
