Experimental vs. simulation analysis of LoRa for vehicular communications

摘要: Abstract LoRa, a Low Power Wide Area Network (LPWAN) technology, demands reduced network infrastructure to cover large area, with low power consumption. In the context of vehicular communications, LoRa has potential support monitoring and cooperative navigation applications, where small amounts data can be transmitted asynchronously through network. Nevertheless, literature lacks evaluations in communications. Thus, this paper we analyze performance technology operating an urban mobility environment, using terminal devices embarked on vehicles receiver unit, acting as infrastructure. Moreover, evaluate equivalence between experimental simulated results, obtained from communication link module inside vehicle comparing those produced by NS-3 simulations. Three metrics interest are evaluated: Packet Delivery Ratio (PDR), Inter-Reception (PIR) time, Received Signal Strength Indicator (RSSI). Field experiments performed at campus Federal University Rio de Janeiro (UFRJ), Brazil. Results revealed that all evaluated consistent results real experiments, however, concluded model improved looking for stronger correlation experiments.
