This paper addresses the design of multiple access protocol for healthcare Internet of things
(HIoT) networking, where devices are massively deployed to facilitate ubiquitous service …

Since massive number of User Equipment (UE) s will cause more collisions and increase
delay, improved Random Access (RA) methods have been researched and proposed. With …

This paper investigates a massive non-orthogonal multiple access (NOMA) enhanced
Internet of Things (IoT) network. In order to provide massive connectivity, a novel cluster …

In the context of massive machine-type communications (mMTCs), the narrowband Internet-
of-Things (NB-IoT) technology is envisioned to efficiently and reliably deal with massive …

Due to the explosive growth in the number of wireless devices and diverse wireless
services, such as virtual/augmented reality and Internet-of-Everything, next-generation …

Cellular-based networks are expected to offer connectivity for massive Internet of Things
(mIoT) systems. However, their Random Access CHannel (RACH) procedure suffers from …

With the growth in global network users over the last several decades, the different Internet
of Things (IoT) technologies and applications have seen strong demand. The IoT has …
