A Scheduling Algorithm for Minimizing the Packet Error Probability in Clusterized TDMA Networks

EURASIP Journal on Wireless Communications and Networking, 2009
We consider clustered wireless networks, where transceivers in a cluster use a time-slotted mechanism (TDMA) to access a wireless channel that is shared among several clusters.

A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and

Management of Invasive Pulmonary Aspergillosis in Intensive Care Units: Guidelines From the Fungal Infection Network of Switzerland (FUNGINOS)

Mycoses, Volume 68, Issue 11, November 2025.
ABSTRACT Invasive pulmonary aspergillosis (IPA) is increasingly recognised in intensive care units (ICU) affecting not only patients with classical immunosuppressive conditions but also other severely ill patients, including those with respiratory viral infections (influenza, COVID‐19), advanced chronic obstructive pulmonary disease or acute and ...

Investigating Aerosol Hygroscopicity in the Subcloud Transition Zone and at the Surface in the Southern Great Plains

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 17, 16 September 2025.
Abstract Aerosols beneath a cloud base, a subcloud transition zone (SCTZ), are key to understand both the aerosol‐cloud interaction and aerosol‐radiation interactions. Lidars have been the primary means of observing aerosols in the SCTZ by virtue of enhanced light scattered by aerosol particles.

Joint Subcarrier Allocation and Beamforming Optimization for IRS‐Assisted Multiuser MISO‐OFDMA Systems

Transactions on Emerging Telecommunications Technologies, Volume 36, Issue 7, July 2025.
We introduce a novel model of an IRS‐assisted MU‐MISO‐OFDMA system. We aim to jointly optimize beamforming vectors, IRS reflection coefficients, and OFDM subcarrier allocation to maximize the overall sum rate. ABSTRACT In this article, we propose a novel resource allocation strategy for multiuser multiple‐input single‐output orthogonal frequency ...

Towards Optimal Distributed Node Scheduling in a Multihop Wireless Network through Local Voting

, 2017
In a multihop wireless network, it is crucial but challenging to schedule transmissions in an efficient and fair manner. In this paper, a novel distributed node scheduling algorithm, called Local Voting, is proposed. This algorithm tries to semi-equalize
