FragCast: A Scalable BLE‐Based OTA Framework for Constrained IoT Devices

IET Wireless Sensor Systems, Volume 16, Issue 1, January/December 2026.
In this research work, we propose and evaluate a novel OTA protocol that leverages the one‐to‐many broadcast paradigm of BLE. Our contribution is an application‐layer protocol that transports firmware fragments within custom‐formatted BLE advertising packets.

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

Sensors, 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.

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

IEEE 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.

Towards a Collision-Free WLAN: Dynamic Parameter Adjustment in CSMA/E2CA

EURASIP Journal on Wireless Communications and Networking, 2011
Carrier sense multiple access with enhanced collision avoidance (CSMA/ECA) is a distributed MAC protocol that allows collision-free access to the medium in WLANs.

CSMA/ECA in Non-Saturation

CoRR, 2013
During the past month we have been trying to understand both the behavior of CSMA/ECA and how our simulator works. In this report I try to asses some of those doubts and provide a groundwork for discussion of past and new ideas for further develop the MAC protocol.

Study on Additional Carrier Sensing for IEEE 802.15.4 Wireless Sensor Networks

Sensors, 2010
Wireless sensor networks based on the IEEE 802.15.4 standard are able to achieve low-power transmissions in the guise of low-rate and short-distance wireless personal area networks (WPANs).
