A Novel Relay Selection and Spectrum Allocation Method for Energy Harvesting Cognitive Device‐to‐Device Network Based on Coalition Game

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
With the large‐scale popularity of wireless terminals, user equipment (UE) puts forward higher requirements for wireless network service quality. By using device‐to‐device (D2D) communication technology for cooperative relay transmission, any UE can be used as a potential relay UE (RUE).

⁠Performance Enhancement of Cell Edge Users in NOMA Based Systems Using Fractional Frequency Reuse

Journal of Sensors, Volume 2026, Issue 1, 2026.
Nonorthogonal multiple access (NOMA) causes significant performance loss for cell‐edge users due to strong intercell interference and fairness constraints under dense deployments. Although fractional frequency reuse (FFR) to improve dependability, especially for cell‐edge users, is widely researched, joint optimization with SINR‐based zoning and NOMA ...

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

A Sub‐Optimum Algorithm for Turning On/Off Co‐Channel Access Points in Ultra‐Dense Networks

Engineering Reports, Volume 7, Issue 11, November 2025.
In the proposed seven‐step Kuhn–Munkres–based resource allocation algorithm, users are initially assigned to access points that support higher data rates while accounting for interference from all access points. Next, only the interference from the selected access points is considered to identify users connected to these access points who meet the ...
