Nowadays, the low-power long-range networks are required for the Internet of Things applications, in which devices can transmit data over long distances and consume low energy. Low-Power Wide-Area Networks (LPWANs) have emerged to focus on a group of …
Widely usage of LPWAN networks allows us to think about the further development of this technology, which develops networks to work not only with the star topology but also with a mesh topology. With such development, a procedure should be provided …
In this paper, we consider the LoRa technology to expand sensor network coverage in smart sustainable cities. A model of a LoRa mesh network is proposed using the AODV protocol in packet routing. With a simulation model developed based on OMNET++, a …
In the last decade, the Internet of Things (IoT) technologies have brought a lot of applications in different fields. Many communication technologies have been developed in order to connect everything to each other and to the Internet. Besides, the …
