A Wireless Protocol for Smart Manufacturing using LoRa at 2.4 GHz

This thesis proposes a new medium access control protocol which lies on top of LoRa at 2,4 GHz. Its name is LoRaIN and, in fact, it is intended for a monitoring Industrial Internet of Things application. First, this document provides a general description of the network architecture and relative functionalities. In particular, the centralized nature of the protocol is described in detail, being a discriminating factor with the others IIoT layer 2 protocols. A fundamental feature of LoRaIN is that the devices are not battery driven and, conversely, they are charged via Wireless Power Transfer technology. In fact, an important emphasis is given to the time division between nodes charges and LoRa communications. Finally, some numerical computations have been performed to show the network performance; the latter have been taken as reference for the hands-on work.
