“…Note that the RACH success probability of a randomly chosen IoT device in networks with perfect PRACH root sequence planning could be obtained by only considering the intra-cell interference. Considering that the practical Voronoi cells do not have a constant radius, we use the average radius D = 1/ √ πλ B [18] to approximate it 4 . Thus, the RACH success probability is given in the following Lemma 3.…”

NarrowBand-Internet of Things (NB-IoT) is a new 3GPP radio access technology designed to provide better coverage for a massive number of low-throughput low-cost devices in delay-tolerant applications with low power consumption. To provide reliable connections with extended coverage, a repetition transmission scheme is introduced to NB-IoT during both Random Access CHannel (RACH) procedure and data transmission procedure. To avoid the difficulty in replacing the battery for IoT devices, the energy harvesting is considered as a promising solution to support energy sustainability in the NB-IoT network. In this work, we analyze RACH success probability in a selfpowered NB-IoT network taking into account the repeated preamble transmissions and collisions, where each IoT device with data is active when its battery energy is sufficient to support the transmission. We model the temporal dynamics of the energy level as a birth-death process, derive the energy availability of each IoT device, and examine its dependence on the energy storage capacity and the repetition value. We show that in certain scenarios, the energy availability remains unchanged despite randomness in the energy harvesting. We also derive the exact expression for the RACH success probability of a randomly chosen IoT device under the derived energy availability, which is validated under different repetition values via simulations. We show that the repetition scheme can efficiently improve the RACH success probability in a light traffic scenario, but only slightly improves that performance with very inefficient channel resource utilization in a heavy traffic scenario.

Low-power Wide Area Networks (LPWANs) constitute a type of networks which is used to connect things to the Internet from a wide variety of sectors. These types of technologies provide the Internet of Things (IoT) devices with the ability to transmit few bytes of data for long ranges, taking into consideration minimum power consumption. In parallel, IoT applications will cover a wide range of human and life needs from smart environments (cities, home, transportation etc.) to health and quality of life. Among these popular LPWANs technologies, we have identified the unlicensed frequency band (LoRa, DASH7, SigFox, Wi-SUN, etc.), and the licensed frequency band standards (NB-IoT, LTE Cat-M, EC-GSM-IoT, etc.). In general, both types of standards only consider fixed interconnected things, and less attention has been provided to the mobility of the things or devices. In this paper, we address the mobility of the things and the connectivity in each of the three LPWAN standards: LoRaWAN, DASH7, and NB-IoT. In particular, we show how the mobility of things can be achieved when transmitting and receiving data. Then, we provide a general and technical comparison for the three standards. Finally, we illustrate several application scenarios where the mobility is required, and we show how to select the most suited standard. We also discuss the research challenges and perspectives.

Asimismo, Díaz-Zayas et al (2016), proponen un análisis a la estandarización planteada por el 3GPP de añadir el soporte aplicaciones IoT bajo LTE. En este trabajo se explica la evolución de LTE para soportar IoT, lo que ha llevado a un aumento de la vida útil de la batería de los dispositivos IoT en el orden de años, reducida complejidad, mayor cobertura y alta densidad de nodos.…”

La tendencia actual es interconectar cualquier dispositivo para ser monitoreado y controlado de manera remota por medio de tecnologías propias del concepto de IoT. Uno de los problemas es conectar los dispositivos a una red mediante tecnologías con suficiente cobertura y capacidad, por lo que en el presente artículo se muestra el desarrollo de un gateway móvil para aplicaciones IoT bajo la plataforma Android, evaluado en redes móviles de 4G. El gateway móvil IoT envía los datos recolectados de sensores mediante la selección de los protocolos MQTT y HTTP, hacia plataformas IoT en Internet. La arquitectura se compone de sensores de temperatura, luminosidad y presión que se integran en un nodo sensor, cuya función es la obtención de los datos, procesamiento y luego, mediante Bluetooth, se envía a un smartphone Android, donde se ejecuta una aplicación que hace la función gateway móvil. Aquí se realiza el entramado de datos que son enviados mediante la red 4G LTE hacia las plataformas IoT de Ubidots y Watson IoT. Posteriormente se realizaron pruebas con varias métricas como latencia, demanda de corriente y costos de conexión. Se concluye que el gateway móvil IoT tiene un mejor rendimiento bajo el protocolo MQTT, en comparación con HTTP.
