“…This capability is crucial for improving network performance through hotspot resolution, topology optimization, congestion reduction, and energy savings. LoRa, typically used in static settings, also finds relevance in mobile scenarios such as fleet monitoring, bike rentals [32], and wildlife tracking, indicating the need for exploring mobility models in LoRa networks [21]. The authors of [33] explored a QoS-aware adaptive mobility method in LoRa-based IoT, focusing on the impact of mobile node configurations on network reliability and efficiency.…”

Long Range (LoRa) as a low-power wide-area technology is distinguished by its robust long-distance communications tailored for Internet of Things (IoT) networks. Because LoRa was primarily designed for stationary devices, when applied to mobile devices, they become susceptible to frequent channel attenuation. Such a condition can result in packet loss, higher energy consumption, and extended transmission times. To address these inherent challenges posed by mobility, we propose an adaptive mobility-based IoT LoRa clustering communication (AMILCC) scheme, which employs the 2D random waypoint mobility model, strategically partitions the network into optimal spreading factor (SF) regions, and incorporates an adaptive clustering approach. The AMILCC scheme is bolstered by a hybrid adaptive data rate (HADR) mechanism categorized into two approaches, namely intra-SF and inter-SF region HADRs, derived from the standard network-based ADR mechanism for stationary devices, to ensure efficient resource allocation for mobile IoT LoRa devices. Evaluation results show that, based on simulations at low mobility speeds of up to 5 m/s, AMILCC successfully maximizes the packet success ratio to the gateway (GW) by over 70%, reduces energy consumption by an average of 55.5%, and minimizes the end-to-end delay by 47.62%, outperforming stationary schemes. Consequently, AMILCC stands as a prime solution for mobile IoT LoRa networks by balancing the high packet success ratio (PSR) with reliability with energy efficiency.

Behavioural Factors for Users of Bicycles as a Transport Alternative: A Case Study

et al. 2022

Recent mobility and transportation dynamics have shaped the main sustainability problems of today, evidencing the need to potentiate alternative, flexible, environmentally friendly transportation means—such as bicycles—that significantly contribute to the health and well-being of users. However, in cities that are just beginning to implement bicycle systems or are seeking to achieve high levels of bicycle use, it is important to know which are the most relevant factors that users consider when using this type of medium. Therefore, the objective of this study was to identify the main behavioural factors among users of the public bicycle programme EnCicla in the city of Medellín, Colombia. Confirmatory factor analysis of responses to a self-administered questionnaire, elaborated based on the Theory of Planned Behaviour, was conducted using the statistical tool Statistical Product and Service Solutions (SPSS). Among the main results, the behavioural factors that further explained behavioural intention were attitude towards behaviour and perceived behavioural control, with values of 0.579 and 0.519, respectively (Cramér coefficient or Cramér’s V). The relevance of these factors lies in the implementation of dynamics that affect a better assessment by users of public bicycles in the EnCicla system, increasing satisfaction with the service and promoting greater adoption in the context of current mobility needs. The practical implications of this study are related to the possibility of designing strategies and public policies to enhance this means of transport in the cities where it is implemented, or to prepare a possible implementation in those that plan to do so.

“…There are four main GNSS systems currently in operation: GPS (U.S.), GLONASS (Russia), Beidou (China), and Galileo (E.U.). These systems, typically, present accuracies in the magnitude order of 1 to 10 m, and have been used in IoT applications that demand higher accuracies and low device autonomy [11]. However, they present some important drawbacks that make them inappropriate for general IoT/IIoT outdoor localization: (1) they consume a lot of power (IoT systems have power battery limitation); (2) they are expensive (IoT localization methods should be low cost), and (3) they provide location information only for the IoT device itself, meaning that additional data must be forwarded to the gateways consuming additional power and bandwidth.…”

GNSS-Free Outdoor Localization Techniques for Resource-Constrained IoT Architectures: A Literature Review

et al. 2021

Large-scale deployments of the Internet of Things (IoT) are adopted for performance improvement and cost reduction in several application domains. The four main IoT application domains covered throughout this article are smart cities, smart transportation, smart healthcare, and smart manufacturing. To increase IoT applicability, data generated by the IoT devices need to be time-stamped and spatially contextualized. LPWANs have become an attractive solution for outdoor localization and received significant attention from the research community due to low-power, low-cost, and long-range communication. In addition, its signals can be used for communication and localization simultaneously. There are different proposed localization methods to obtain the IoT relative location. Each category of these proposed methods has pros and cons that make them useful for specific IoT systems. Nevertheless, there are some limitations in proposed localization methods that need to be eliminated to meet the IoT ecosystem needs completely. This has motivated this work and provided the following contributions: (1) definition of the main requirements and limitations of outdoor localization techniques for the IoT ecosystem, (2) description of the most relevant GNSS-free outdoor localization methods with a focus on LPWAN technologies, (3) survey the most relevant methods used within the IoT ecosystem for improving GNSS-free localization accuracy, and (4) discussion covering the open challenges and future directions within the field. Some of the important open issues that have different requirements in different IoT systems include energy consumption, security and privacy, accuracy, and scalability. This paper provides an overview of research works that have been published between 2018 to July 2021 and made available through the Google Scholar database.
