Two-Slot Based Model of the IEEE 802.11ah Restricted Access Window with Enabled Transmissions Crossing Slot Boundaries
P. 1–9.
Recently appeared the IEEE 802.11ah standard has introduced a new channel access mechanism, so-called Restricted Access Window (RAW). This mechanism allows an access point (AP) to reduce contention for the channel in overloaded Wi-Fi networks by limiting the number of stations simultaneously accessing the channel. The 802.11ah AP divides all associated stations into groups and allocates for each group an interval of time, which is called a RAW slot. This paper considers the RAW mechanism with enabled transmissions crossing slot boundaries, which means that a station is allowed to end the current transmission attempt even after a completion of the allocated RAW slot. We present a new mathematical model, which allows estimating throughput and energy consumption with this mechanism, and optimizing performance of RAW.

This paper examines the problem of clustering consumption patterns for a private household. An ensemble algorithm based on the Wasserstein metric was developed and applied to cluster daily load profiles. The proposed approach allows for identifying typical energy consumption scenarios and interpreting consumer behavior. Results from computational experiments using real data are presented. ...

This paper considers an Industrial Internet of Things (IIoT) scenario, where wireless devices embedded with sensors are deployed over an industrial machine, and transmit the measured data to a final Gateway (GW) using Terahertz (THz) frequencies. To mitigate the path loss of such high frequencies, the GW is equipped with multiple radiating elements, thereby generating ...

This paper considers a model of the Internet of Things (IoT) system with a potentially unlimited number of devices. In such systems, a large number of conflicts arises that leads to retransmissions of messages. A large number of retransmissions causes transmitter operation time growth. More transmitting time in turn increases energy consumption and reduce device ...

IEEEThe paper describes an online deep learning algorithm (ODL) for adaptive modulation and coding in massive MIMO. The algorithm is based on a fully connected neural network, which is initially trained on the output of the traditional algorithm and then incrementally retrained by the service feedback of its output. We show the advantage of our ...
