Determining real-time communication feasibility in IoT systems supported by LoRaWAN
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-04-26)
Article
Accés obertLoRaWAN 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 ... -
Reliability analysis in a wireless ISP
(2023-03-14)
Report de recerca
Accés obertThis brief report investigates different quality parameters to assess the reliability in Wireless Internet Service Providers, WISPs. In our analysis we use a Markov chain approach. We investigate the time to failure, failure ... -
Circular consumption and production of electronic devices: an approach to measuring durability, upgradeability, reusability, obsolescence and premature recycling
(Institut universitari de recerca en Ciència i Tecnologies de la Sostenibilitat (ISST.UPC), 2019)
Text en actes de congrés
Accés obertWhat is circular consumption of electronics? Is it measurable? Can we set goals or compare with other consumers? A principle of circular economy is durability, prolonging the useful life of products. If we move the principle ... -
