“…In [11], the authors evaluate the use of IEEE 802.15.4g for environmental observations. The results show that the longest radio links were obtained when using SUN-FSK or SUN-OQSPK, since these radio settings have the highest sensitivity for the transceiver used in the experiments.…”

Adaptive mechanisms, such as channel hopping and packet duplication, are used in low-power wireless networks to deal with the spatial and temporal variations in the link quality, and meet the reliability requirements of industrial applications (i.e., PDR>99%). However, the benefits of such mechanisms are limited and may have a large impact on end-to-end latency and energy consumption. Hence, in this paper we propose using adaptive modulation diversity, which allows to dynamically select different modulation, to improve link reliability. We present three adaptive modulation diversity selection strategies and validate them using the data derived from a real-world deployment using the IEEE 802.15.4g SUN modulations (i.e., SUN-FSK, SUN-OQPSK and SUN-ODFM) in an industrial environment. The results show that by using adaptive modulation diversity it is possible to improve link reliability regardless of node conditions.

“…Transmit power depends on regional regulations, but must be at least −3dBm [5]. Most configurations use 14dBm transmit power and 1% duty cycle [21]. IEEE 802.15.4G proposes extensions to the MAC mechanisms defined by IEEE 802.15.4E amendment [22] and makes extensive use of low-energy modes.…”

Smart Utility Networks (SUN) rely on the Wireless-SUN (WI-SUN) specification for years. Recently, however, practitioners and researchers have also considered Low-Power Wide-Area Networks (LPWAN) like LORAWAN for such applications. With distinct technologies deployed in the same area and sharing unlicensed bands, one can expect these networks to interfere with one another. This paper builds over a LORAWAN model to optimize network parameters while accounting for the interference from other technologies. Our analytic model accounts for the interference LORAWAN receives from IEEE 802.15.4G networks, which form the bottom layers of WI-SUN systems. We also derive closed-form equations for the expected reliability of LORAWAN in such scenarios. We set the model parameters with data from real measurements of the interplay among the technologies. Finally, we propose two optimization algorithms to determine the best LoRaWAN configuration given a targeted minimum reliability level as a restriction. The first algorithm maximizes communication range given a constraint on the minimum number of users, and the second maximizes the number of users given a minimum communication range. We validate the models and algorithms through numerical analysis and simulations. The proposed methods are useful tools for planning interferencelimited networks with requirements of minimum reliability.

In this article we present a deployment of 11 nodes using the three different SUN (Smart Utility Network) modulation schemes, as defined in the IEEE 802.15.4-2015 standard. The nodes were deployed in a 110.044 m2 warehouse for 99 days, and the resulting dataset contains a total of 10.710.868 measurements with RSSI (Received Signal Strength Indicator), CCA (Clear Channel Assessment) and PDR (Packet Delivery Ratio) values. The analyzed results show a high variability in average RSSI (i.e., between -82.1 dBm and -101.7 dBm) and CCA (i.e., between -111.2 dBm and -119.9 dBm) values, which are caused by the effects of multi-path propagation and external interference. Despite being above the sensitivity limit for each modulation, this values result in poor average PDR values (i.e., from 65.9% to 87.4%), indicating that additional schemes are required for low-power wireless communications to meet the dependability requirements of industrial applications. For that purpose, we also introduce the concept of modulation diversity, which can be combined with packet repetition to meet such requirements (i.e., PDR>99%) while minimizing the energy expenditure of nodes and meeting regulatory constraints.
