Ambient intelligence (AmI) represents the future vision of intelligent computing that can bring
intelligence to our daily life through various domains. In such applications, AmI is often …

Given the proliferation of the massive machine type communication devices (MTCDs) in
beyond 5G (B5G) wireless networks, energy harvesting (EH) aided next generation multiple …

This paper investigates a multi-node wireless powered communication network (WPCN),
where a hybrid access point (HAP) first charges an Internet of Thing (IoT) device wirelessly …

Many applications operating in the Internet of Things (IoT) require timely and fair data
collection from devices. This has motivated research into a new metric called Age of …

In the Industrial Internet of Things (IIoT), non-orthogonal multiple access (NOMA) has
emerged as a viable multiple access method due to its superior efficiency. In this paper, a …

Most existing optimization objectives considered in non-orthogonal multiple access (NOMA)
power allocation schemes are non-delay-sensitive metrics. In order to apply NOMA to …

In this paper, we aim to minimize the age of information (AoI) for a random access internet of
things (IoT) network, where AoI is a metric to measure the freshness of information delivery …

In this paper, we consider two different classes of IoT sensors with high and low priorities in
which both classes send their data to a Monitoring Center (MC) equipped with one server …

Concurrent communication constitutes one of the challenging issues associated with IoT
networks, as it is highly likely that multiple devices may start communication simultaneously …

Along with the development of realtime applications, the freshness of information becomes
significant because the overdue information is worthless and useless and even harmful to …
