Simulation of scalability in IoT applications

Abstract:

The deployment of a wireless sensor and actuator network (WSAN) in IoT applications is a complex task. The need to establish the number of nodes, sensors and actuators, as well as their location and characteristics, requires a tool that allows preliminary determination of these data. In addition, because of the IoT scenarios where present a large number of sensors and actuators, it is necessary to analyze the scalability of these systems. This article proposes the study of the scalability of IoT Applications by means of simulation techniques. The Ptolemy II simulation tool and a real MQTT message broker were used. The authors present a case study related to the deployment of networks of sensors and actuators as an integral part of an IoT application to monitor and control the parks of a city. Experimental results demonstrate that the use of simulation techniques allow to analyze the scalability of this type of applications.
