Abstract:
Internet of Things (IoT) is gaining more impact on our lives and has been increasingly used. It allows several wireless devices to be connected, and their distance can range from a few inches to many miles. New IoT technologies such as LoRa are emerging allowing energy efficient wireless communication over exceptionally long distances. So, it is particularly important to evaluate its performance through simulations. At this purpose, it is possible to find several tools and simulators for LoRa technology. All of them present distinctive features and are written with different programming languages with the possibility to enable and disable different features. In this paper it is analysed in detail the Simulator LoRaEnergySim, which allows the creation of a network with only one Gateway (GTW). In addition, the simulator is extended considering the case of Multi-GTW presence with very high IoT node density and considering all interference aspects that can be related to this new scenario
. Besides, the extended simulator, considers now the imperfect orthogonality of the Spreading Factor (SF) not fully supported in the previous simulator version with the aim to consider more realistic simulations.
