Special Issue Information

Dear Colleagues,

The "Internet of Things (IoT)" has experienced substantial growth around the globe. The various applications of IoT include smart and urban cities, wearable health monitoring devices, smart homes and buildings, smart cars, environment monitoring, intelligent border security, and logistics support. The IoT proposes numerous smart objects, such as sensors, actuators, embedded systems, and other similar items, that are prevalent in their surroundings. Ubiquitous connections, falling prices for smart devices, and a high demand for data all testify to the IoT's continued rapid expansion. On the basis of the IoT paradigm, numerous sectors are redesigning their business models. However, how well the IoT is deployed will be determined by the development of several problem solutions.  

Various IoT environment faces multiple constraints, such as erratic connection, privacy, trust issues, data analysis, or lengthy round-trip durations. Multiple research projects are being conducted to address these challenges and develop advanced IoT ecosystems. The objective is to allow the next generation of IoT applications, which have semi-autonomous behavior, which develops while keeping humans informed and involved as a key component of the system.

The special issue's goal is to compile reviews and contributions on cutting-edge scientific and technical techniques, best practices, and innovations related to IoT sensors for sensing, applications, and developments. Through the creation of a large collection of articles showcasing recent advancements, fresh experiences, and innovative ideas, this special issue aims to cultivate and gather knowledge in this context for the benefit of industrial practice and research.

Designing and deploying telecommunications and broadcasting networks in the challenging terrain of the Amazon region pose significant obstacles due to its unique morphological characteristics. Within low-power wide-area networks (LPWANs), this research study introduces a comprehensive approach to modeling large-scale propagation loss channels specific to the LoRaWAN protocol operating at 915 MHz. The objective of this study is to facilitate the planning of Internet of Things (IoT) networks in riverside communities while accounting for the mobility of end nodes. We conducted extensive measurement campaigns along the banks of Universidade Federal do Pará, capturing received signal strength indication (RSSI), signal-to-noise ratio (SNR), and geolocated point data across various spreading factors. We fitted the empirical close-in (CI) and floating intercept (FI) propagation models for uplink path loss prediction and compared them with the Okumura–Hata model. We also present a new model for path loss with dense vegetation. Furthermore, we calculated received packet rate statistics between communication links to assess channel quality for the LoRa physical layer (PHY). Remarkably, both CI and FI models exhibited similar behaviors, with the newly proposed model demonstrating enhanced accuracy in estimating radio loss within densely vegetated scenarios, boasting lower root mean square error (RMSE) values than the Okumura–Hata model, particularly for spreading factor 9 (SF9). The radius coverage threshold, accounting for node mobility, was 945 m. This comprehensive analysis contributes valuable insights for the effective deployment and optimization of LoRa-based IoT networks in the intricate environmental conditions of the Amazon region.

Rural communities in Mexico and other countries with limited economic resources require a low-cost measurement system for the piezometric level and temperature of groundwater for their sustainable management, since anthropogenic action (pumping extractions), natural recharge and climate change phenomena affect the behavior of piezometric levels in the aquifer and its sustainability is at risk. Decrease in the piezometric level under a balanced level promotes salt intrusion from ocean water to the aquifer, salinizing and deteriorating the water quality for agriculture and other activities; and a decrease in water level under the pumps or well drilling depth could deprive communities of water. Water temperature monitoring is essential to determine electric conductivity and dissolved salt content in groundwater. Using IoT technology, a device was developed that monitors both variables inside the well, and the ambient temperature and atmospheric pressure outside the well. The measurements are made in real time, with sampling every second and sending data to a dedicated server every 15 min so that the visualization can be accessed through a device with Internet access. The time series of the variables measured inside and outside the well were obtained over a period of three months in the rural community of Agua Blanca, Guasave, Sinaloa, Mexico. Through these records, a progressive temporary drawdown of the piezometric level is observed, as well as the frequency of pumping. This low-cost IoT system shows potential use in hydrological processes of interest such as the separation of regional and local flow, drawdown rates and recognition of geohydrological parameters.
