Comparison Between Different Types of Sensor Architecture Using a Uniform Relay Protocol

摘要

Organizations want to collect data remotely to predict incidents or simply to store and analyze them. To do that, a sensor network is often deployed to collect these data. However, the dynamic nature of these networks and possible sensors out of range must be taken into account to ensure that information retrieval is carried out correctly. The main solution used by the operator is a star topology. An architecture that is simple to deploy but which does not always make it possible to reach all the sensors, such as those located in cellars or tunnels. In this paper, we propose a study of a relay protocol including a local synchronization solution on different platforms to evaluate the power consumption of many types of sensor architecture and communication technology. The platforms considered using the following microcontroller: STMicroelectronics STM32, LoPy, and Arm® Cortex®-M3 with Texas Instrument CC1350 with the 3 following modulation wireless communications: LoRa, WIFI, and raw 868MHz.
