“…To this end, LoRa multi-hop network topologies are considered as a method to boost up performance especially for such end nodes [ 19 , 54 , 123 , 124 , 125 ]. In other studies, the LoRaWAN end nodes were extended with relying capabilities [ 126 ].…”

LoRaWAN is one of the low power wide area network (LPWAN) technologies that have received significant attention by the research community in the recent years. It offers low-power, low-data rate communication over a wide range of covered area. In the past years, the number of publications regarding LoRa and LoRaWAN has grown tremendously. This paper provides an overview of research work that has been published from 2015 to September 2018 and that is accessible via Google Scholar and IEEE Explore databases. First, a detailed description of the technology is given, including existing security and reliability mechanisms. This literature overview is structured by categorizing papers according to the following topics: (i) physical layer aspects; (ii) network layer aspects; (iii) possible improvements; and (iv) extensions to the standard. Finally, a strengths, weaknesses, opportunities and threats (SWOT) analysis is presented along with the challenges that LoRa and LoRaWAN still face.

“…In the literature there are several studies related to object and environmental monitoring by means of LoRa, concerning agriculture and livestock farming [19,21,[23][24][25], health [26], forestry [12,27], smart cities [2,28], industrial [4,5,29] and maritime [9] applications.…”

“…Another evaluation of the feasibility of LoRa transmission in an industrial scenario has been carried out in [29], where the authors experimented time-slotted channel-hopping to respect the limitations imposed by spectrum access regulations and to improve the typical node latency down to less than one minute, which is deemed to be acceptable for most industrial control applications. The authors of [4] also proposed the adoption of an enhanced flexible node to supplement gateway functionalities and to act as a range extender. In [9], maritime communication with boats is established using LoRa, in particular for lightweight boats navigating near the coastal line.…”

“…In the above presented LoRaWAN approaches [2,4,5,12,21,[23][24][25][26][27][28][29], the adopted LoRaWAN MAC layer does not include a listen-before-talk (LBT) mechanism that tries to prevent as much as possible packet collisions among nodes [34]. On the contrary, our paper proposes a custom MAC layer that includes LBT-based carrier-sense multiple access with collision avoidance (CSMA/CA), to be incorporated with the physical layer of LoRa.…”

“…With the diffusion of the Internet-of-Things (IoT) paradigm [1], objects are being connected to the Internet, thus realizing a global network of connected things. This new concept is being used in several scenarios, such as in smart cities [2,3], industrial manufacturing [4,5], healthcare [6,7] and transportation [8,9]. Another application scenario is in rural areas [10,11], and specifically on smart livestock farming [12], over which we focus our work.…”

An IoT Architecture for Continuous Livestock Monitoring Using LoRa LPWAN

et al. 2019

The Internet of Things (IoT) architecture is quickly becoming popular even outside of its originating scenario of home automation. This paper reports the design, implementation, and performance of an IoT hardware and software architecture conceived for the continuous monitoring of livestock located in barns and during grazing. We have adopted the LoRa low power wide area network (LPWAN) technology to cover the diverse environments, and a suitable configuration of web services to perform data storage, analysis, and visualization. Since the LoRa LPWAN (LoRaWAN) medium access control (MAC) layer does not provide a listen-before-talk (LBT) mechanism, we propose a custom MAC layer with LBT-based carrier-sense multiple access with collision avoidance (CSMA/CA). The devised system has been implemented using off-the-shelf hardware, and its performance has also been estimated with the help of a C++ event-based simulator. The preliminary results of our HW implementation on the field confirm the stability of the conceived system and its reliability. suburban or rural environments [15], making this technology viable for both small and medium-scale applications. It has also been shown that a single LoRa gateway can manage a large number of EDs with little maintenance and easy deployment [5].LoRa is a proprietary wireless communication standard developed by Semtech, based on a chirp spread spectrum (CSS) modulation [16,17]. The physical layer (PHY) uses chirp waveforms with different chirp rate, to maintain orthogonality among different classes of users, and with different initial frequency, to convey the actual information message [15]. Channel coding is also used, with interleaving and Hamming block codes. Although the details of the LoRa PHY are not public, several authors have tried and succeeded to reverse-engineer, almost completely, its PHY communication techniques [18].On the other side, LoRaWAN is an open MAC protocol, built on top of the LoRa PHY, that is specifically designed for low-powered devices operating over long-range wireless links. Even though LoRaWAN is commonly used in deploying LoRa networks [19], in this work we have decided to implement a custom MAC layer in order to have more control over the architectural design and to remove some features of the LoRaWAN layer [20] that are not used in our application, such as the large header size when short payloads have to be delivered, and the packet acknowledgments managed by a LoRa server. Continuous and near-real-time monitoring of livestock, in particular of dairy cattle, can help to provide information vital to study the animal behavior and to prevent pathological states that have a negative impact on livestock health [21,22].In particular, our proposed architecture aims at analyzing, almost in real-time, the status of dairy cattle in a cowshed or during grazing by means of sensors embedded in smart collars. By the way, this approach may be extended also to other kinds of livestock, such as beef cattle, swine, ovine, and even equine.In this paper we first de...
