Dynamic-Persistent CSMA: A Reinforcement Learning Approach for Multi-User Channel Access

open access: yesIEEE Access
This paper addresses the challenge of multiple users concurrently sharing a single channel in a wireless network, a problem typically managed by Carrier Sense Multiple Access (CSMA) protocols.

Nanomaterial‐Based Precision Medicine for Breast Cancer Diagnosis and Treatment

open access: yesChemNanoMat, Volume 11, Issue 11, November 2025.
This research emphasizes the use of targeted precision medicine in the treatment of breast cancer. Through the integration of diagnosis and therapeutic delivery, nanocarriers are designed to selectively target cancer cells, preserving healthy tissue, thereby improving treatment effectiveness and reducing side effects.

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.

A Proximity based Retransmission Scheme for Power Line Ad-hoc LAN

open access: yes, 2010
Power line as an alternative for data transmission is being explored, and also being used to a certain extent. But from the data transfer point of view, power line, as a channel is highly dynamic and hence not quite suitable.

Throughput-Optimal Random Access with Order-Optimal Delay

open access: yes, 2010
In this paper, we consider CSMA policies for scheduling of multihop wireless networks with one-hop traffic. The main contribution of this paper is to propose Unlocking CSMA (U-CSMA) policy that enables to obtain high throughput with low (average) packet ...

Stability and throughput improvement for multichannel CSMA and CSMA/CD protocols with optimal bandwidth allocation [PDF]

open access: yesProceedings Third IEEE Symposium on Computers and Communications. ISCC'98. (Cat. No.98EX166), 2002
Summary: This paper examines appropriate protocols for high-speed multiple access communication systems where the bandwidth is divided into two separate asymmetric channels. Both channels operate using slotted non-persistent CSMA or CSMA/CD techniques. The free stations access the first channel while all retransmissions occur in the second channel.
