Deep multi‐agent RL for anti‐jamming and inter‐cell interference mitigation in NOMA networks
IET Communications, Volume 19, Issue 1, January/December 2025.Four multi‐agent reinforcement learning algorithms: Q‐learning based unselfish (QLU), deep QLU, hot booting deep QLU, and decreased state deep QLU. We also provide a game‐theoretic analysis that demonstrates the algorithms' convergence to the optimal network‐wide strategy with high probability.

An Auction Approach to Spectrum Management in HetNets
CoRR, 2017 The growing demand in mobile Internet access calls for high capacity and energy efficient cellular access with better cell coverage. The in-band relaying solution, proposed in LTE-Advanced, improves coverage without requiring additional spectrum for backhauling, making its deployment more economical and practical. However, in-band relay without careful

QoE‐based dynamic resource allocation for heterogeneous smart distribution grids
IET Communications, Volume 19, Issue 1, January/December 2025.This article introduces an innovative metric termed as Quality of Experience (QoE) by amalgamating the terminal operations concerning data rate, latency, and packet loss rate. With the aim of maximizing the QoE, we design a dynamic resource allocation scheme in a heterogeneous wireless communication and power line communication network.

IET Communications, Volume 19, Issue 1, January/December 2025.This paper presents SAMA, a simulator for 5G Radio Access Networks (RAN), designed to evaluate the performance of different network configurations. The diagram illustrates the simulator's workflow: from inputs such as base station (BS) and user equipment (UE) arrangements, SAMA simulates resource allocation and scheduling, considering interference.
