Introduction
I work in embedded development and R&D for Aloxy in Antwerp, Belgium. I am coming to the end of my PhD in wireless communications from Maynooth University in Ireland. My research focuses on enabling scalable and energy efficient LPWAN networks, in particular LoRaWAN, and have extensive experience with ns-3. My research interests include next generation Wi-Fi, low power IoT networks, energy harvesting approaches for LPWAN, and the simulation of wireless networks.

Article
Full-text available
The progressive adoption of Wi-Fi networks in commercial verticals (dense deployments in buildings, robotics control, gaming) is leading to densification, which demands improvements in reliability and performance guarantees (improved throughput with low latency). Based on these requirements, the IEEE 802.11 working group aims to develop a new amend...
Article
Environmental monitoring is an important application for wireless sensing devices. Battery power requires in-the-field replacement, and the chemicals involved are environmentally harmful, so harvested energy is a useful alternative. Previous research has shown the feasibility of powering LoRaWAN sensors using high-energy ambient or wireless transfe...
Conference Paper
Massive Machine Type Communications is a wireless paradigm which focuses on traffic that is transmitted by a huge number of low cost, low power, infrequently transmitting devices. LoRaWAN, a Low Power Wide Area Network technology, is particularly suited to contribute to coverage of this form of traffic. In this work, we introduce a novel, lightweig...
Article
The Adaptive Data Rate algorithm is a key component of the LoRaWAN protocol which controls the performance of a LoRaWAN Network. This modifies the data rate parameter of a device based on the current wireless conditions. In this paper, we present substantive enhancements for the End Device and Network Server which reduce the convergence time for Lo...
Conference Paper
Full-text available
New wireless technologies have been developed in recent years which enable applications that require the transmission of small amounts of data over long distances in an energy efficient manner. One of these technologies, LoRaWAN, includes a server-initiated communication mode named Class B which provides a deterministic latency for downlink communi...
Conference Paper
Full-text available
LPWAN technologies are defined by their focus on extended coverage while maintaining energy efficiency, at the expense of data throughput. In this research we enable the analysis of LoRa, a key LPWAN technology, in terms of energy efficiency. We perform real-world measurements of a standard LoRa chip and use the results to develop an energy consump...
Poster
New wireless technologies have been developed in recent years to enable applications which require the transmission of small amounts of data over long distances in an energy efficient manner (LPWANs). The LPWAN technology which has attracted significant attention in research, LoRaWAN, includes a server-initiated communication mode named Class B whi...
Conference Paper
Full-text available
The unique challenges posed by the breadth of Internet of Things applications have resulted in the development of a number of different Low Power Wide Area wireless solutions. These technologies enable scalable long range networks on cheap low power devices, facilitating the development of a ubiquitous Internet of Things. The energy efficiency of t...
Article
Full-text available
Motivated by the increasing variance of suggested Internet of Things (IoT) applications and the lack of suitability of current wireless technologies in scalable, long range deployments, a number of diverging Low Power Wide Area (LPWA) technologies have been developed. These technologies promise to enable a scalable high range network on cheap low p...
