Irregular repetition slotted ALOHA (IRSA) based non-orthogonal multiple access (NOMA)
with priority adaptive traffic load (ATL)(PATL-IRSA-NOMA) is proposed to prioritize the …

In this paper, we study a joint user pairing and power allocation problem in the 5th
generation (5G) satellite random access (RA) networks, where some user equipments (UEs) …

Non-orthogonal multiple access (NOMA) techniques can recover collided signals
simultaneously transmitted from different users that select different target received signal …

Irregular repetition slotted Aloha (IRSA) has shown significant advantages as a modern
technique for uncoordinated random access with massive number of users due to its …

In this paper, we study via simulation the performance of irregular repetition slotted ALOHA
under multi-packet detection and different patterns of the load process. On the one hand, we …

In this article, we propose an optimal irregular repetition slotted ALOHA (IRSA) under total
transmit power constraint for random access (RA) in the Internet-of-Things (IoT)-oriented …

In the past few years, the continual improvement of 5G technology has supported powerful
IoT (Internet of Things) and IIoT (Industrial IoT) devices which have been used to provide a …

In irregular repetition slotted ALOHA (IR-SA) systems, a population of devices transmits their
packets to an access point (AP) within a frame of slots. The AP decodes these packets by …

In the visionary ideals of “Internet of Everything” and “Digital Twins”, the future 6G will deeply
integrate diverse heterogeneous networks such as satellite and aerial networks to support …

In this paper, we propose a spatial group based optimal uplink power control scheme to
enhance the performance of random access (RA) in satellite networks. In the proposed …
