Machine to machine (M2M) communications is one of the key underpinning technologies for Internet of Things (IoT) applications in 5G networks. The large scale of M2M devices imposes challenge on conventional medium access control protocols. In this paper, we propose a reinforcement learning (RL) based duty cycle control for dominant short-range technology IEEE 802.15.4 to provide high performance and...
IEEE 802.15.4 beacon-enabled mode adopts duty cycle to achieve energy efficiency and provides an optional acknowledgement (ACK) mechanism to ensure the transmission reliability. However, frequently sending ACK introduces additional ACK transmission energy consumption and increases end-to-end delay. In this paper, we focus on a duty cycle optimisation problem with joint consideration on energy efficiency,...
