A Support Tool for Rapid Deployment of Large Scale Distributed Sensing Systems

Abstract

Distributed sensing systems are spatially distributed autonomous sensing devices for environmental observation purposes in large areas. In recent years, the innovation of embedded sensing devices and wireless communication have been developed rapidly. It allows for improving the capability of processing and reducing energy consumption for a long time, wireless sensor networks (WSNs) in order to meet a wide range of applications. Besides wide-range coverage, LoRa technology also provides the benefits of low power consumption, scalability and interference immunity for wireless links. This paper proposes a support tool for the rapid deployment of large scale distributed sensing systems based on LoRa technology. The major motivation behinds this work is to help designer select the proper set of parameters for improving the performance of LoRa systems taking into account the strong impact of geographic topology. The experiments on a star LoRa network for environmental data dissemination was done to evaluate the effectiveness of the tool on the reduction of packet transmission time, known as time-on-air (ToA).
