Coded Slotted ALOHA with Varying Packet Loss Rate across Users

open access: yes, 2013
The recent research has established an analogy between successive interference cancellation in slotted ALOHA framework and iterative belief-propagation erasure-decoding, which has opened the possibility to enhance random access protocols by utilizing ...

MAC Protocol Design for Optical Wireless Body‐Area Networks: Latency, Energy Efficiency and Scalability Analysis

open access: yesIET Networks, Volume 15, Issue 1, January/December 2026.
This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

Multi-slot Coded ALOHA with Irregular Degree Distribution [PDF]

open access: yes, 2012
This paper proposes an improvement of the random multiple access scheme for satellite communication named Multislot coded ALOHA (MuSCA). MuSCA is a generalization of Contention Resolution Diversity Slotted ALOHA (CRDSA).

Exploiting in-Slot Micro-Synchronism for S-ALOHA

open access: yesIEEE Transactions on Wireless Communications, 2022
Proliferation of the urban Internet-of-Things (IoTs) for smart cities has fuelled massive amounts of data over wireless cellular networks. Random access (RA) system of wireless cellular networks, e.g., 5G New Radio (NR), based on S-ALOHA system should cope with ever-growing IoT traffic.

HLH‐30/TFEB Rewires the Chaperone Network to Promote Proteostasis Upon Perturbations to the Coenzyme A and Iron–Sulfur Cluster Biosynthesis Pathways

open access: yesAging Cell, Volume 24, Issue 6, June 2025.
Proteostasis enhancing treatments are potential therapies for many age‐related diseases. We discovered that interference with the CoA biosynthesis pathway and limiting iron‐sulfur cluster availability improve proteostasis in C. elegans. Proteostasis improvement under these conditions depends on the conserved HLH‐30/TFEB transcription factor, which ...

A Power Dissipation Comparison of the R-TDMA and the Slotted-Aloha Wireless MAC protocols [PDF]

open access: yes, 1997
In this paper two wireless multiple-access protocols are compared by their power dissipation for the uplink traffic of a wireless networks. After briefly discussing the behaviour of the Slotted Aloha protocol (Abramson, 1985) and the R-TDMA protocol ...
