Computing Nash Equilibrium in Wireless Ad Hoc Networks: A Simulation-Based Approach [PDF]

Electronic Proceedings in Theoretical Computer Science, 2012
This paper studies the problem of computing Nash equilibrium in wireless networks modeled by Weighted Timed Automata. Such formalism comes together with a logic that can be used to describe complex features such as timed energy constraints.

Injectable Biomimetic Composite Hydrogel Scaffold With Tissue‐Engineered Cartilage Matrix for Articular Cartilage Regeneration

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Articular cartilage regeneration remains a significant challenge because of its limited intrinsic healing capacity and the inadequacy of conventional treatments for restoring structural and functional integrity. In this study, a novel injectable composite hydrogel scaffold was designed to mimic the extracellular matrix (ECM) of native ...

CSMA: A Standalone and ImageJ-Compatible Tool for Enhanced Wound Healing Assay Analysis

IEEE Access
Accurate quantification of wound closure in cell migration assays is crucial yet challenging. Still, existing methods often underperform due to omitting cell detection within the wound area, resulting in biased outcomes.

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

Analysis of Access Delay and Delay Jitter for the CSMA/CA Mechanism with Inactive Period [PDF]

Radioengineering, 2019
Owing to the distributed features and flexibility, carrier sense multiple access with collision avoidance (CSMA/CA) mechanisms have been widely adopted in wireless networks. Considering energy consumption, we devote to explore an energy efficient carrier

Free Energy Approximations for CSMA Networks [PDF]

2017 IEEE 25th International Symposium on Modeling, Analysis, and Simulation of Computer and Telecommunication Systems (MASCOTS), 2017
In this paper we study how to estimate the back-off rates in an idealized CSMA network consisting of $n$ links to achieve a given throughput vector using free energy approximations. More specifically, we introduce the class of region-based free energy approximations with clique belief and present a closed form expression for the back-off rates based on

Exploring Missed Spectrum Access Opportunities in Wi‐Fi 6 and 5G NR‐U Coexistence for Enhancing 6 GHz Spectrum Utilization

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...
