System-Level Evaluation of Uplink Access Schemes for Ambient IoT
Douglas Dziedzorm Agbeve, Henrique Duarte Moura, Andrey Belogaev +1
Ambient Internet of Things (A-IoT) devices operate under stringent energy constraints, relying on harvested power in the W-to-mW range and limited energy storage. The A-IoT air…
To GAN or Not To GAN: Segmentation Analysis on Mars DEM
Douglas Dziedzorm Agbeve, Aditya V. Handrale, Salim Fares +1
To better understand Martian Surface, which is needed to enable Rovers navigate Mars with ease, it is necessary to be able to determine the location of mounds. Detecting and studyi…
Evaluating UORA-Based Polling Mechanism for Latency-Sensitive Uplink Traffic in Wi-Fi Networks
Douglas Dziedzorm Agbeve, Andrey Belogaev, Chris Blondia +1
IEEE 802.11ax (Wi-Fi 6) introduced Orthogonal Frequency Division Multiple Access (OFDMA), which enables simultaneous transmissions through centralized resource allocation. However,…
Design and Evaluation of IEEE 802.11ax Uplink Orthogonal Frequency Division Multiple Random Access in ns-3
Douglas Dziedzorm Agbeve, Andrey Belogaev, Jeroen Famaey
Wi-Fi networks have long relied on the Enhanced Distributed Channel Access (EDCA) mechanism, allowing stations to compete for transmission opportunities. However, as networks becom…
A2P: A Scalable OFDMA Polling Algorithm for Time-Sensitive Wi-Fi Networks
Douglas Dziedzorm Agbeve, Andrey Belogaev, Wim Sandra +2
Over the years, advancements such as increased bandwidth, new modulation and coding schemes, frame aggregation, and the use of multiple antennas have been employed to enhance Wi-Fi…
