“…The standard specifies different modes able to operate in different frequency bands, including the Sub-GHz ISM bands used by LORAWAN. Data rates range from 40 to 1000 kbps, depending on the modulation and bandwidth in use [19].…”

“…Multi-Rate FSK (MR-FSK), with 2-FSK or 4-FSK, is the predominant modulation version in SUN applications due to its communication range [20]. In this configuration, the transceiver combines FSK modulation with Frequency Hopping Spread Spectrum (FHSS) to increase robustness [19]. The data rate may vary from 2.4 to 200 kbps, depending on region and frequency band.…”

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.

“…This standard can be characterized between WSN and LPWAN. The technology modulates with FSK in the free ISM 800-900 MHz, offers a data rate up to 150 kbit/s, and reaches nodes up to 5 km away [30]. For the sake of completeness, the Weightless [31] LPWAN technologies should also be mentioned.…”

Standards for Cyber-Physical Energy Systems—Two Case Studies from Sensor Technology

Cyber-physical energy systems (CPES) describe a specialization of the cyber-physical system concept, in which energy systems are transformed into intelligent energy networks. These systems provide the basis for the realization of smart microgrids and smart grids. In the last decade, numerous research projects have intensively explored the fundamentals and modeling of CPES and validated them in pilot projects. In the meantime, more and more CPES solutions have been appearing on the market and the battle for the most suitable standards has begun. This paper gives an overview of the currently available standards for CPES sensor technologies and assesses the suitability for implementation. In two case studies in the application area of operational energy management in German companies, a sensor retrofitting is described-once with proprietary technology and once using the standards Long Range (LoRa) Wide Area Network and OPC Unified Architecture (OPC UA). As a result, the shortcomings of the standards for their use in CPES are shown and discussed. OPC UA, which was originally developed for the manufacturing industry, turns out to be to be a suitable standard for a wide range of CPES implementations.

“…A especificação Wi-SUN FAN define dois métodos possíveis para roteamento de pacotes IPv6: RPL obrigatório na camada de rede e Multi-Hop Delivery Service (MHDS) opcional na camada de enlace de dados [11]. Como a rede pode operar apenas com um dos métodos, este estudo está dirigido para o primeiro método indicado.…”

Resumo-Wireless Smart Ubiquitous Network Field Area Network (Wi-SUN FAN) é um perfil que faz parte da aliança Wi-SUN que desenvolve especificações para redes de área de campo, suportando Low Power and Lossy Networks (LLNs). O perfil Wi-SUN FAN fornece serviços de transporte baseados em IPv6 e adota o protocolo IPv6 Routing Protocol for LLNs (RPL) para formação e roteamento de pacotes, o qual trabalha na camada de rede. O RPL permite inicialmente a construção da rede antes do envio dos pacotes de dados dentro da rede FAN, utilizando várias métricas para determinar o custo do caminho que conectará os nós uns com os outros. Neste estudo, o RPL foi configurado com os parâmetros definidos pelo WI-SUN FAN. A simulação foi realizada em três cenários com diferentes posicionamentos de nós, utilizando o simulador Cooja. Para avaliação da rede, foram analisados o tempo de convergência da rede, sobrecarga de trafego em referência das mensagens de controle do RPL, latência da rede e taxa de entrega de pacotes para cada cenário.
