Increasing LPWAN Scalability by Means of Concurrent Multiband IoT Technologies: An Industry 4.0 Use Case

One of the most important challenges of the Internet of Things (IoT) in the next years will be the smooth incorporation of millions of smart devices into its communications paradigm. The greater coverage area of sub-1-GHz low-power wide area networks (LPWANs) makes them a suitable technology to easily encompass hundreds of end devices under a single base station. However, LPWAN inherent simplicity affects negatively on scalability, as these networks are not flexible enough to deal with a high number of nodes unless their traffic load is really low, which limits many potential use-cases. This paper analyzes the scalability issue in LPWAN and proposes the INTER-HARE protocol: a solution based on the use of concurrent multiband IoT technologies, where an 868-MHz LPWAN acts as transparent backhaul for a set of subnetworks working at 2.4 GHz. The implementation of the INTER-HARE protocol on a real IoT platform was assessed both in several laboratory testbeds and in a pilot developed in the premises of an industrial company, proving its suitability in non-delay sensitive monitoring applications with end devices scattered throughout the targeted area.

“…The miniaturization of sensors and sensor motes play a key role in the development of wearable systems. Researchers in academia and industries are working in parallel on miniaturization and accuracy of wearable sensors and sensor motes [Hadjidj et al 2012;Patel et al 2012b;Crosby et al 2012;Buckley et al 2012;HERZOG 2013;Honeywell 2014;Peiris 2013]. The wearable photoplethysmograph ring (WPPGR) biomedical sensor developed in [Yang and Rhee 2000] improves wearability.…”

Body Area Networks (BANs) are becoming increasingly popular and have shown great potential in realtime monitoring of the human body. With the promise of being cost effective, unobtrusive, and facilitating continuous monitoring, BANs have attracted a wide range of monitoring applications, including medical and healthcare, sports, and rehabilitation systems. Most of these applications are real-time and life-critical, and require a strict guarantee of Quality of Service (QoS), in terms of timeliness, reliability, etc. Recently, there have been a number of proposals describing diverse approaches or frameworks to achieve QoS in BANs (i.e., for different layers or tiers, different protocols). This survey put these individual efforts into perspective and presents a more holistic view of the area. In this regard, this article identifies a set of QoS requirements for BANs applications and shows how these requirements are linked in a 3-tier BAN system, and presents a comprehensive review of the existing proposals against those requirements. In addition, open research issues, challenges, and future research directions in achieving these QoS in BANs are highlighted.

“…We start by the case where the BS powers the devices using dedicated subcarriers signals. Note that this scenario is appropriate for devices with limited hardware capabilities [32][33][34] typically used for health and fitness (body sensor devices) or industrial IoTs applications. Hardware restrictions limit devices to only tune and communicate over a small number of channels (e.g., the N subcarriers/channels assigned to each user), but not over a large number of channels to cover all the K × N channels used by the BS (as in the second system setup presented in Section IV).…”

Energy harvesting emerges as a potential solution for prolonging the lifetime of the energy-constrained mobile wireless devices. In this paper, we focus on Radio Frequency (RF) energy harvesting for multiuser multicarrier mobile wireless networks. Specifically, we propose joint data and energy transfer optimization frameworks for powering mobile wireless devices through RF energy harvesting. We introduce a power utility that captures the power consumption cost at the base station (BS) and the used power from the users' batteries, and determine optimal power resource allocations that meet data rate requirements of downlink and uplink communications. Two types of harvesting capabilities are considered at each user: harvesting only from dedicated RF signals and hybrid harvesting from both dedicated and ambient RF signals. The developed frameworks increase the end users' battery lifetime at the cost of a slight increase in the BS power consumption. Several evaluation studies are conducted in order to validate our proposed frameworks.
