Matroid Secretary Is Equivalent to Contention Resolution [PDF]

open access: yes, 2022
We show that the matroid secretary problem is equivalent to correlated contention resolution in the online random-order model. Specifically, the matroid secretary conjecture is true if and only if every matroid admits an online random-order contention ...

Generalized Encoding CRDSA: Maximizing Throughput in Enhanced Random Access Schemes for Satellite

open access: yesEAI 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

On Adaptive Contention Resolution Schemes for IEEE 802.16 BWA Systems

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
According to the latest version of the IEEE 802.16 standard, the mandatory contention resolution method is the truncated binary exponential backoff, with the initial window size and the maximum window size controlled by the base station.

Statistical Analysis of a Distributed Queuing Random Access Protocol in a Massive Communication Environment [PDF]

open access: yesEAI 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

Multi-Hop-Enabled Energy-Efficient MAC Protocol for Underwater Acoustic Sensor Networks

open access: yesJournal of Sensor and Actuator Networks, 2015
In multi-hop underwater acoustic sensor networks (UWASNs), packet collisions due to hidden and local nodes adversely affect throughput, energy efficiency and end-to-end delay.

An Efficient Contention Resolution Scheme for Massive IoT Devices in Random Access to LTE-A Networks

open access: yesIEEE Access, 2018
Long-Term Evolution-Advanced (LTE-A) networks have been regarded as having great potential to support the Internet of Things (IoT). However, the high probability of preamble collisions when massive numbers of IoT devices try to access the network within ...

Matroid Secretary Is Equivalent to Contention Resolution

open access: yesCoRR, 2021
We show that the matroid secretary problem is equivalent to correlated contention resolution in the online random-order model. Specifically, the matroid secretary conjecture is true if and only if every matroid admits an online random-order contention resolution scheme which, given an arbitrary (possibly correlated) prior distribution over subsets of ...

Performance Enhancements for Asynchronous Random Access Protocols over Satellite [PDF]

open access: yes, 2011
In this paper, a novel enhancement of the well known ALOHA random access mechanism is presented which largely extends the achievable throughput compared to traditional ALOHA and provides significantly lower packet loss rates. The novel mechanism, called
