Hidden Terminal-Aware Contention Resolution with an Optimal Distribution [PDF]
, 2011 Achieving low-power operation in wireless sensor networks with high data load or bursty traffic is challenging. The hidden terminal problem is aggravated with increased amounts of data in which traditional backoff-based contention resolution mechanisms ...

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

An Efficient Contention Resolution Scheme for Massive IoT Devices in Random Access to LTE-A Networks
IEEE 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 [PDF]
arXiv, 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 ...

Computational structured illumination for high-content fluorescent and phase microscopy [PDF]
Biomed. Opt. Express 10, 1978-1998 (2019), 2018 High-content biological microscopy targets high-resolution imaging across large fields-of-view (FOVs). Recent works have demonstrated that computational imaging can provide efficient solutions for high-content microscopy. Here, we use speckle structured illumination microscopy (SIM) as a robust and cost-effective solution for high-content fluorescence ...

Random Access Game and Medium Access Control Design [PDF]
, 2010 Motivated partially by a control-theoretic viewpoint, we propose a game-theoretic model, called random access game, for contention control. We characterize Nash equilibria of random access games, study their dynamics, and propose distributed algorithms (
