Implementation and Analysis of Routing Protocols for LoRa Wireless Mesh Networks

Abstract

In a world getting more and more connections, the growth in the number of devices sharing information with each other is evident. Therefore, as the number of connected devices and their applications grows, the amount of data shared by these devices also increases considerably. Thus, in order to be able to send data from one device to another and that data passing through intermediate devices, it is necessary to define from which path the data should be sent, characterizing the routing concept. In this context, this work aims to implement and analyze routing protocols for ad hoc wireless network called DVR (Distance Vector Routing), AODV (Ad Hoc On-Demand Distance Vector) and DSR (Dynamic Source Routing) using the Cupcarbon network simulator. LoRa wireless communication technology and a network topology distributed along avenues in the city of João Pessoa, Brazil, were considered and simulated. The quantitative analysis criteria were the packet delivery rate, the average end-to-end delay and throughput. The energy consumption profiles of each network node were also obtained according to each protocol. The results showed that the DSR protocol had lower energy consumption and AODV obtained better general performance, but with higher consumption. The DVR protocol showed better results in terms of latency.
