IPv6 is considered as the most promising approach to enable the interoperability of the future Internet of Things due to its ability to provide sufficient public addresses. At the same time, hierarchical machine-to-machine communications have been identified as the key driver to integrate various IoT applications. This article focuses on wrapping up these technologies to provide seamless and interoperable...
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,...
An experiment system made up of a membrane absorption unit and a membrane vacuum regeneration unit was set up. Ionic liquids (ILs), 1-butyl-3-methyl-imidazolium tetrafluoroborate ([bmim][BF 4 ]) and 1-(3-aminopropyl)-3-methyl-imidazolium tetrafluoroborate ([apmim][BF 4 ]) as two absorbents for CO 2 capture, were applied to the experiment system. Coupling processes of membrane...
An advanced elimination algorithm based on the dynamic PID control concept for treating drift rate effects of MEMS-Based inertial devices, such as accelerometer and gyroscope is proposed in this investigation. Effects of drift rates of inertial devices strongly influence the performance of the relative motion sensing products that are designed by MEMS-based inertial devices, e.g., small regions of...
