Las redes de área amplia de baja potencia (LPWAN) proporcionan un servicio de red de bajo consumo y largo alcance a los dispositivos del Internet de las cosas (IoT). La calidad de servicio (QoS) varía significativamente entre las LPWAN en las bandas de frecuencia con y sin licencia, lo que obliga a elegir entre coste y rendimiento. En este trabajo se examinan los mecanismos que influyen en la QoS en análisis sistemáticos de la banda estrecha IoT (NB-IoT) y de la red de área amplia de largo alcance (LoRaWAN). Los resultados indican que ninguna tecnología puede cubrir todos los casos de uso. Por lo tanto, se propone un novedoso protocolo de agrupación de banda estrecha (NBP), que proporciona un eficiente servicio de transporte multitrayecto a los dispositivos IoT y funciona en una amplia gama de enlaces LPWAN. Los primeros experimentos con un prototipo real demuestran prometedoras mejoras de la QoS.
Low Power Wide Area Networks (LPWANs) provide an energy-efficient and long-range network service to Internet of Things (IoT) devices. The Quality of Service (QoS) varies significantly between LPWANs in the licensed and unlicensed frequency bands, requiring to choose between cost and performance. In this work, the mechanisms that influence the QoS are examined in systematic analyses of Narrowband Internet of Things (NB-IoT) and Long Range Wide Area Network (LoRaWAN). The results indicate that no single technology can cover all use cases. Therefore, the novel Narrowband Bundling Protocol (NBP) is proposed, which provides an efficient multipath transport service to IoT devices and works over a wide range of LPWAN links. First experiments with a real prototype demonstrate promising QoS improvements.
