Random access (RA) has recently been revisited and considered as a key technology for
the medium access control layer of the Internet of Things applications. Compared to other …

This paper proposes a new medium access control (MAC) protocol for Internet of Things
(IoT) applications incorporating pure ALOHA with power domain non-orthogonal multiple …

The Internet of things (IoT), which is the network of physical devices embedded with sensors,
actuators, and connectivity, is being accelerated into the mainstream by the emergence of …

In this letter, a non-orthogonal multiple access (NOMA) scheme is employed for irregular
repetition slotted ALOHA (IRSA). Specifically, packet replicas are transmitted with discrete …

Internet of Things devices communicate using a variety of protocols, differing in many
aspects, with the channel access method being one of the most important. Most of the …

In nonorthogonal multiple access (NOMA), the power difference of multiple signals is
exploited for multiple access and successive interference cancellation is employed at a …

In this article, we consider the massive nonorthogonal multiple access (NOMA) with a hybrid
automatic repeat request (HARQ) for short packet communications. To reduce the latency …

Non-orthogonal multiple access (NOMA) as an efficient method of radio resource sharing
has its roots in network information theory. For generations of wireless communication …

The Internet of Things (IoT) has significant importance in the beyond fifth generation (B5G)
communication systems. However, the IoT is vulnerable to disasters because the network is …

Massive machine-type communications (mMTC) is one of the main three focus areas in the
5th generation (5G) of wireless communications technologies to enable connectivity of a …
