Performance analysis of access class barring for next generation IoT devices
Alexandria Engineering Journal, 2021 Massively dense deployment of Internet of Things (IoT) devices has put a stringent requirement on cellular networks to provide convenient service for not only human type traffic (HTC) but also for bursty traffic for IoT devices.

Sign-Compute-Resolve for Tree Splitting Random Access [PDF]
, 2018 We present a framework for random access that is based on three elements: physical-layer network coding (PLNC), signature codes and tree splitting. In presence of a collision, physical-layer network coding enables the receiver to decode, i.e.

Strategic Contention Resolution with Limited Feedback [PDF]
CoRR, 2016 In this paper, we study contention resolution protocols from a game-theoretic perspective. We focus on \emph{acknowledgment-based} protocols, where a user gets feedback from the channel only when she attempts transmission. In this case she will learn whether her transmission was successful or not.

Is Our Model for Contention Resolution Wrong?
, 2017 Randomized binary exponential backoff (BEB) is a popular algorithm for coordinating access to a shared channel. With an operational history exceeding four decades, BEB is currently an important component of several wireless standards.

Pairwise-independent contention resolution
Mathematical ProgrammingAbstract We study online contention resolution schemes (OCRSes) and prophet inequalities for non-product distributions. Specifically, when the active set is sampled according to a pairwise-independent (PI) distribution, we show a $$(1-o_k(1))$$ (

A Node-Regulated Deflection Routing Framework for Contention Minimization
Journal of Computer Networks and Communications, 2020 Optical Burst Switching (OBS) paradigm coupled with Dense Wavelength Division Multiplexing (DWDM) has become a practical candidate solution for the next-generation optical backbone networks. In its practical deployment only the edge nodes are provisioned

Unbounded Contention Resolution in Multiple-Access Channels [PDF]
Algorithmica, 2011 A frequent problem in settings where a unique resource must be shared among users is how to resolve the contention that arises when all of them must use it, but the resource allows only for one user each time. The application of efficient solutions for this problem spans a myriad of settings such as radio communication networks or databases.

IEEE Access, 2023 In satellite Internet-of-Things (IoT) systems using the 920-MHz band Low Power Wide Area, available channels for each terminal are limited to avoid interference with terrestrial networks. Since this limitation depends on the location of the terminal, the

Optimum Header Positioning in Successive Interference Cancellation (SIC) based Aloha
, 2013 Random Access MAC protocols are simple and effective when the nature of the traffic is unpredictable and sporadic. In the following paper, investigations on the new Enhanced Contention Resolution ALOHA (ECRA) are presented, where some new aspects of the ...
