摘要: The Internet of Things paradigm aims to connect a very large number smart objects located all around the world for increasing knowledge about environment. Low-power wireless communications are compulsory reduce object invasiveness and ensure reasonable duration autonomous node. For this reason, several Low-Power Wide-Area Network (LPWAN) technologies have been proposed in recent past, because their range low consumption. Most notably, LoRaWAN solution emerged as most accepted LPWAN research works appeared, discussing its advantages limitations. However, few, if any, discuss timing performance real scenario, considering not only frontend but also wired backend. In work, authors implement use case based on public infrastructure propose metrics formally evaluate delays at application level (i.e. whole black box). result is an average delay 400-700 ms, proof that directly dependent both backend connection speed information endpoints.
