Performance Analysis of TDMA Protocol in a Femtocell Network [PDF]
Mehran University Research Journal of Engineering and Technology, 2014 In this paper, we evaluate the performance of TDMA (Time Division Multiple Access) protocol using queuing theory in a femtocell network. The fair use of wireless channel among the users of network is carried out using TDMA protocol.

Open vs Closed Access Femtocells in the Uplink
, 2010 Femtocells are assuming an increasingly important role in the coverage and capacity of cellular networks. In contrast to existing cellular systems, femtocells are end-user deployed and controlled, randomly located, and rely on third party backhaul (e.g ...

IET Networks, Volume 15, Issue 1, January/December 2026.This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

ASO-TDMA: ad-hoc self-organizing TDMA protocol for shipborne ad-hoc networks [PDF]
EURASIP Journal on Wireless Communications and Networking, 2012 A shipborne ad-hoc network (SANET), a maritime counterpart of the terrestrial vehicle ad-hoc network, can provide ships with diverse multimedia services by substituting digital maritime VHF communications for expensive satellite communications. This article proposes ad-hoc self-organizing TDMA (ASO-TDMA), a medium access control (MAC) protocol ...

IET Networks, Volume 15, Issue 1, January/December 2026.This paper proposes a reconfigurable intelligent surface‐based deep reinforcement learning MAC (RIS‐DRL‐MAC) protocol for terahertz mesh networks. By embedding RIS perception into the MAC decision loop and using a distributed TD3 algorithm, the proposed scheme achieves a cross‐layer optimisation of beam direction, access timing and RIS phase control ...

Increase the Life of the Wireless Sensor Network by using an Energy-Sensitive Threshold Cross-layer Model [PDF]
International Journal of Information and Communication Technology ResearchWireless sensor networks (WSNs) are advanced tools for monitoring and controlling the environment, which are powered by a limited capacity battery, and the depletion of the sensor battery leads to the end of the life of the network life. Therefore, it is

Design and Optimization of Finite Alphabet Waveforms for Multiple‐Antenna Radar Covariance Matching
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article propose a novel method for finite‐alphabet waveform generation based on constrained matrix decomposition. It also expands theoretical feasibility bounds for generating covariance matrices with binary waveforms, proves that matrices from autoregressive processes are always realizable and introduces an optimal adjustment procedure for ...
