CNDS - Xarxes de Computadors i Sistemes Distribuïts
Les xarxes comunitàries busquen una xarxa oberta, lliure i neutral aplicant el principi de
reciprocitat a la interconnexió de nodes per la circulació de continguts i serveis. El grup
investiga on Xarxes Comunitàries (Community Networks), Computació en Núvol Comunitària
(Community Clouds) i Xarxes De Sensors Sense Fils Comunitàries (Community Wireless Sensor
Networks).

IoT-based surveillance camera distribution using triangle geometry
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Comunicació de congrés
Accés obertIoT systems provide excellent solutions to many applications in both civilian and military aspects. This is even facilitated by the advent of many types of cameras with the diminishing cost of communication devices. We ... -
Property rights in servitisation: a practical assessment with reused computers
(Springer, 2022)
Text en actes de congrés
Accés obertThe circular economy of computers is about producing fewer, more durable and reusable products while investing in expanding their life span through a functional service economy. Reuse is often mentioned as a sustainable ... -
Charging of the ABR service in ATM networks: a numerical example
(Institute of Electrical and Electronics Engineers (IEEE), 1998-04)
Article
Accés obertThe 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
Accés obertMany 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 ... -
Position paper: LoRa mesh networks for enabling distributed intelligence on tiny IoT nodes
(IOS Press, 2023)
Capítol de llibre
Accés obertLoRaWAN is a widely used solution in today’s Internet of Things (IoT) applications to connect remote sensor nodes to the Internet. At the same time, microcontroller-based sensor nodes with increased processing capacities ... -
Server-side adaptive federated learning over wireless mesh network
(Springer, 2023)
Capítol de llibre
Accés restringit per política de l'editorialIn federated learning, distributed nodes train a local machine learning model and exchange it through a central aggregator. In real environments, these training nodes are heterogeneous in computing capacity and bandwidth, ... -
Integrating a neural network library in embedded federated learning
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertFederated learning has become a popular collaborative machine learning approach in which clients use their local data for training. This results in bandwidth savings since the training data does not have to be transferred ... -
Stateful adaptive streams with approximate computing and elastic scaling
(Association for Computing Machinery (ACM), 2023)
Comunicació de congrés
Accés obertThe model of approximate computing can be used to increase performance or optimize resource usage in stream and graph processing. It can be used to satisfy performance requirements (e.g., throughput, lag) in stream processing ... -
Exploring blockchain-based management for LoRa IoT nodes
(Springer, 2023)
Text en actes de congrés
Accés obertWe consider open IoT applications in which the IoT devices, i.e. sensor nodes and gateways, can be contributed by volunteer participants. Since the contribution of sensor deployments and their data is critical for the value ... -
Robust proxy sensor model for estimating black carbon concentrations using low-cost sensors
(Association for Computing Machinery (ACM), 2023)
Comunicació de congrés
Accés obertAir quality monitoring sensor networks focusing on air pollution measure pollutants that are regulated by the authorities, such as CO, NO2, NO, SO2, O3, and particulate matter (PM10, PM2.5). However, there are other ... -
Dataset for anomaly detection in a production wireless mesh community network
(Elsevier, 2023-08)
Article
Accés obertWireless 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
Accés obertIn 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 ...
