Leveraging spatiotemporal correlations with recurrent autoencoders for sensor anomaly detection
(Institute of Electrical and Electronics Engineers (IEEE), 2024-10-01)
Article
Open AccessThe introduction of high- and low-cost Internet of Things (IoT) sensors in air quality monitoring networks, in addition to providing a cost-effective solution for monitoring pollutant levels, also brings with it the challenge ... -
A case for research with and on community networks
(2013-07)
Article
Open AccessCommunity Networks are large scale, self-organized and decentralized networks, built and operated by citizens for citizens. In this paper, we make a case for research on and with community networks, while explaining the ... -
Estimating black carbon levels using machine learning models in high-concentration regions
(Elsevier, 2024-10-20)
Article
Open AccessBlack carbon (BC) is emitted into the atmosphere during combustion processes, often in conjunction with emissions such as nitrogen oxides (NOx) and ozone (O3), which are also by-products of combustion. In highly polluted ... -
A minimalistic distance-vector routing protocol for LoRa mesh networks
(Institute of Electrical and Electronics Engineers (IEEE), 2024-08-14)
Article
Open AccessLoRa is popular in the Internet of Things (IoT) domain as a Low Power,Wide Area Network (LPWAN) radio technology, providing low-power and long-range communication in the sub-GHz band. Most often, LoRa is used as part of ... -
eXO: a commons-based community network Internet Service Provider, description and subscribers usage patterns
(2024-12)
Article
Open AccessThe advent of Wi-Fi in the 1990s stimulated the creation of Community networks (CNs), a new networking paradigm deployed and maintained by their users. The non-profit and grassroots self-organization of CNs has shown ... -
A data-driven framework for air quality sensor networks
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-11)
Article
Open AccessIn this article, we present our research vision of a framework for obtaining quality data in air quality monitoring networks using low-cost sensors (LCSs). The use of LCS networks is gaining increasing acceptance in many ... -
Toward smart community networks
(Institute of Electrical and Electronics Engineers (IEEE), 2023-03)
Article
Open AccessThe advent of IEEE 802.11 in the late 1990s spurred the development of new network paradigms. In particular, new technology enthusiasts saw the potential of Wi-Fi to bring broadband Internet connections to under-provisioned ... -
Charging of the ABR service in ATM networks: a numerical example
(Institute of Electrical and Electronics Engineers (IEEE), 1998-04)
Article
Open AccessThe Available Bit Rate service (ABR) is a "best effort" service intended for traffic which imposes no bound on delay or delay variation. The network guarantees a Minimum Cell Rate (MCR) for an ABR source, which is negotiated ... -
The effects of weight quantization on online federated learning for the IoT: a case study
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-04)
Article
Open AccessMany weight quantization approaches were explored to save the communication bandwidth between the clients and the server in federated learning using high-end computing machines. However, there is a lack of weight quantization ... -
Dataset for anomaly detection in a production wireless mesh community network
(Elsevier, 2023-08)
Article
Open AccessWireless community networks, WCN, have proliferated around the world. Cheap off-the-shelf WiFi devices have enabled this new network paradigm where users build their own network infrastructure in a do-it-yourself alternative ... -
Embedded federated learning over a LoRa mesh network
(Elsevier, 2023-06)
Article
Open AccessIn on-device training of machine learning models on microcontrollers a neural network is trained on the device. A specific approach for collaborative on-device training is federated learning. In this paper, we propose ... -
Determining real-time communication feasibility in IoT systems supported by LoRaWAN
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-04-26)
Article
Open AccessLoRaWAN is a long range and low power protocol devised for connecting devices under the Internet of Things (IoT) paradigm. This protocol was not conceived to support real-time message delivery; therefore, it is not always ...
