Wraz z dynamicznym rozwojem Internetu Rzeczy (IoT), wzrasta potrzeba stosowania coraz to nowszych energooszczędnych rozwiązań komunikacyjnych. Sieci LPWAN (ang. Low-Power Wide-Area Network) umożliwiają niskoenergetyczną komunikację dalekiego zasięgu. Istotnym jest by nowe rozwiązania cechowały się łatwością konfiguracji umożliwiającą szybkie wdrożenie. W artykule dokonano przeglądu platform do komunikacji urządzeń IoT w standardzie LoRaWAN (ang. LoRa Wide Area Network) pod kątem stopnia złożoności konfiguracji. Opisano sposób konfiguracji budowanego na Wydziale Informatyki i Telekomunikacji, Politechniki Poznańskiej eksperymentalnego systemu LPWAN do badań związanych z Inteligentnymi budynkami.

With the rapid growth of the Internet of Things (IoT), there is a growing need for newer energy-efficient communication solutions. Low-Power Wide-Area Networks (LPWAN) enable low-energy long-range communication. It is important for new solutions to be easy to configure and quick to implement. The paper reviews platforms for IoT device communication in LoRaWAN (LoRa Wide Area Network) standard in terms of configuration complexity. The paper describes the configuration of an experimental LPWAN system being built at the Faculty of Computing and Telecommunications, Poznan University of Technology for research related to Intelligent buildings.
A key role in the development of smart Internet of Things (IoT) solutions is played by wireless communication technologies, especially LPWAN (Low-Power Wide-Area Network), which are becoming increasingly popular due to their advantages: long range, low power consumption and the ability to connect multiple edge devices. However, in addition to the advantages of communication and low power consumption, the security of transmitted data is also important. End devices very often have a small amount of memory, which makes it impossible to implement advanced cryptographic algorithms on them. The article analyzes the advantages and disadvantages of solutions based on LPWAN communication and reviews platforms for IoT device communication in the LoRaWAN (LoRa Wide Area Network) standard in terms of configuration complexity. It describes how to configure an experimental LPWAN system being built at the Department of Computer Science and Telecommunications at Poznan University of Technology for research related to smart buildings.
In order to develop reliable safety standards for 5G sensor networks (SN) and the Internet of Things, appropriate verification tools are needed, including those offering the ability to perform automated symbolic analysis process. The Tamarin prover is one of such software-based solutions. It allows to formally prove security protocols. This paper shows the modus operandi of the tool in question. Its application has been illustrated using an example of an exchange of messages between two agents, with asynchronous encryption. The scheme may be implemented, for instance, in the TLS/DTLS protocol to create a secure cryptographic key exchange mechanism. The aim of the publication is to demonstrate that automated symbolic analysis may be relied upon to model 5G sensor networks security protocols. Also, a use case in which the process of modeling the DTLS 1.2 handshake protocol enriched with the TCP SYN Cookies mechanism, used to preventing DoS attacks, is presented.
