Distributed Call Admission Control for DESYNC-TDMA in Mobile Ad Hoc Networks

open access: yesEAI Endorsed Transactions on Mobile Communications and Applications, 2016
DESYNC-TDMA is a self-organizing algorithm based on bio-inspired features used to implement a collision-free MAC. It does not require a global clock or other infrastructures, and it automatically adjusts to the number of participating nodes to ensure ...

Centralized Energy Harvesting-Based TDMA Protocol for Terahertz NanoSensor Networks

open access: yesSensors, 2019
Terahertz wireless nano-sensor networks (WNSNs) are novel networks interconnecting multiple nano-devices by means of wireless communication. In this paper, a centralized energy harvesting-based time division multiple access (TDMA) protocol, called CEH ...

Time Slot Utilization for Efficient Multi-Channel MAC Protocol in VANETs

open access: yesSensors, 2018
In vehicular ad hoc networks (VANETs), many schemes for a multi-channel media access control (MAC) protocol have been proposed to adapt to dynamically changing vehicle traffic conditions and deliver both safety and non-safety packets.

Intelligent TDMA heuristic scheduling by taking into account physical layer interference for an industrial IoT environment [PDF]

open access: yes, 2017
In an Internet of Things environment, where multiple mobile devices are brought together, it is not always possible to serve all these devices simultaneously. We developed an intelligent Time Division Multiple Access (TDMA) scheduler which allows to plan

Sub-optimality of Treating Interference as Noise in the Cellular Uplink [PDF]

open access: yes, 2011
Despite the simplicity of the scheme of treating interference as noise (TIN), it was shown to be sum-capacity optimal in the Gaussian 2-user interference channel in \cite{ShangKramerChen,MotahariKhandani,AnnapureddyVeeravalli}.

Hybrid NOMA-TDMA for Multiple Access Channels with Non-Ideal Batteries and Circuit Cost

open access: yes, 2018
We consider a multiple-access channel where the users are powered from batteries having non-negligible internal resistance. When power is drawn from the battery, a variable fraction of the power, which is a function of the power drawn from the battery ...

Physical Channel Access (PCA): Time and Frequency Access Methods Simulation in NS-2 [PDF]

open access: yes, 2013
We present an NS-2 module, Physical Channel Access (PCA), to simulate different access methods on a link shared with Multi-Frequency Time Division Multiple Access (MF-TDMA). This technique is widely used in various network technologies, such as satellite
