    This regional project (B-TIC-568-UGR20) is titled "LoRaWAN sensors network for enviromental monitoring in rural and urban areas" (PREMONITION). It started on July 2021 and it will end on June 2023.

Description

    This project proposes an LPWAN (Low-Power Wide Area Network) network architecture based on the LoRaWAN (Long Range Wide Area Network) standard with the objective of collecting environmental information for different key environments within the priorities and challenges for Andalusia, such as natural spaces, agricultural and aquaculture farms in rural areas, and smart cities in urban areas. This information will be collected through the use of low-cost IoT (Internet of Things) sensors, which must be energy efficient (to be able to use batteries for years) and which can be at great distances (several kilometers from the deployed infrastructure).

    The proposed network architecture consists of several parts. First, a radio access network based on LoRaWAN. Second, a core network which will allow the communication between the radio access network and the LoRaWAN servers, based on an SDN (Software Defined Networking) network. The LoRaWAN servers will be implemented following the NFV (Network Functions Virtualization) paradigm.

    Both the proposed architecture and the solutions developed will be implemented in a testbed or prototype network, in order to verify the viability of the solution and to provide a demonstrator for the project.

    This article proposes a system based on a long-distance communications system with low economic and energy costs that allows connectivity to be carried out independently from the existing cellular coverage in the area. In addition, it describes the design, development, implementation and analysis of an Internet of Things (IoT) architecture based on Long-Range Wide-Area Network (LoRaWAN). Moreover, the system has been deployed as a prototype, and the behavior and scope of the system have been analyzed in various real environments: urban, rural and natural. The results obtained from the analysis show that the system is suitable for working in areas without coverage such as mountains.

    In this work, an architecture for IoT networks oriented towards environmental sustainability is presented. Due to the suitability of its characteristics in terms of coverage, power and support of a large number of devices, an enhanced LoRaWAN network has been chosen as the basis for this proposal. The architecture is completed with the virtualization of the different LoRaWAN network entities and the usage of a software-defined network for their interconnection. The publication and subscription to environmental data is carried out by using the MQTT protocol. MQTT has been optimized thanks to the use of the SDN network and the use of edge computing resources, which allows multicasting of published data. Thanks to our developed MQTT2MULTICAST protocol, latency is improved by approx. 90% and the traffic load within the SDN network is reduced by 55%. An scalability analysis shows that this solution is able to support tens of thousands of LoRaWAN gateways. The proposed architecture has been implemented using commercial equipment as a proof of concept.
