An Optimal Greedy Algorithm for the Single Access Contention Resolution Problem
IEEE Access, 2019 We present the greedy optimal algorithm for contention resolution (GOAL-CR), a greedy algorithm that solves a variant of the standard contention resolution problem where a set of nodes want to access a shared resource only once, and the objective is to ...

Analysis of the Distributed Queueing Algorithm in a Multichannel Network with Mixed-Type Traffic [PDF]
EAI Endorsed Transactions on Internet of Things, 2021 Networks such as LTE-M, NB-IoT, LoRa and SigFox are being deployed for massive IoT communications. However, the Aloha protocols used for the media access are inefficient when the network size is high.

Investigation of Contention or Appositional Function in Persian Grammar [PDF]
Literary Arts, 2022 The grammatical argument of contention means playing two functions by one word or phrase in Persian language sentences. There is ambiguity and disagreement in Persian grammar articles and books about contention or the appositional function.

On the Sum-Rate of Contention Resolution in Massive MIMO With NOMA
IEEE Access, 2021 In this paper, we investigate the random access (RA) problem in a massive MIMO scenario. To deal with the continuous increase in the number of users, and the difficulty associated with sharing pilots among such users in order to organize channel access ...

Generalized Encoding CRDSA: Maximizing Throughput in Enhanced Random Access Schemes for Satellite
EAI Endorsed Transactions on Mobile Communications and Applications, 2014 This work starts from the analysis of the literature about the Random Access protocols with contention resolution, such as Contention Resolution Diversity Slotted Aloha (CRDSA), and introduces a possible enhancement, named Generalized Encoding Contention

Statistical Analysis of a Distributed Queuing Random Access Protocol in a Massive Communication Environment [PDF]
EAI Endorsed Transactions on Internet of Things, 2020 Most of the networks deployed for massive IoT communications use Aloha-based algorithms for channel access. However, those algorithms are known to be unstable and inefficient when the network size is high. Since recently, a Distributed
