Abstract:
Due to scarce energy resources and large power consumptions, Wireless Power Transfer (WPT) technology is gaining increasing interest in 5G networks and the Internet of Things (IoT). However, when data communication is conducted concurrently with WPT, large interference signals may be induced which degrade performance significantly. In LoRaWAN networks, a popular IoT technology, the problem is further exacerbated by the potential of the interference signals to jam the join procedure by flattening the Received Signal Strength (RSS), thus compromising system security. In this work, we develop a mathematical framework which allows the characterization of the join procedure and communication in LoRaWAN networks as a result of the interference effects induced by WPT devices. The conducted analysis and the relevant numerical results are used to characterize the interference effects and join procedure failure ratio with respect to the power, distance and number of WPT devices. The flattening effects of RSS are shown via simulations and its implications on the network security are also demonstrated. The presented work aims at providing design guidelines for the system, so that communication performance degradation as well as network security deterioration as a result of the WPT effects is kept within acceptable levels.
