Multi-Linear LoRa network topology deployment with interference avoidance for white area monitoring

The emergence of the Internet of Things (IoT) has given a new dimension for monitoring applications due in particular to new communication technologies such as LoRa/LoRaWAN. These innovations in the technology have driven the curiosity to use LoRa-based network in applications such as smart agriculture management and monitoring system, road tracks or railways monitoring, border monitoring, Oil and Gas, or even water pipeline supervision, etc. This kind of network is called linear network topology LoRa imposed by the linearity of monitored infrastructure. Some of the challenges faced in a linear network are mainly: interference management, energy efficiency and network lifetime increase.The main goal of this paper is to propose a Linear LoRa sensor network architecture for the monitoring of so-called white areas located on the southern Senegal in West Africa. The simplified architecture is composed by end device nodes and gateways communicating by LoRa radio links. The choice of such a physical topology is explained by the fairly complex nature of the node deployment environment, which is very rugged. The objective of this study is to find a better deployment of nodes to achieve a better coverage of infrastructure deployed in non-connected far areas.
