Co-simulação de rede para Internet das coisas

Abstract

The construction of the co-simulated network (physical network and simulated network) of this thesis will be a basis for the development of simulation techniques using the OMNeT ++ (computational) platform with (physical) sensors. Once the platform is established, it would be possible to extend the operation of the network to other environments, such as the development of physical networks in mining. In this sense we can build a physical network, and simulate the behavior of other components and networks using OMNeT ++. As this work uses IoT for the development of the proposed topology, this work ends up corroborating the use of low power appliances. The objective of this dissertation is to show in a real environment the use of co-simulation with OMNeT ++ to validate the platform created for the production of simulations of IoT networks. In such a way it will be possible to show that the co-simulation works properly in the OMNeT ++ simulations environment, and to provide a basis for possible future expansions. Basically we have a set of components that will be connected to each other wirelessly (creating an RSSF), which will be connected (via TCP / IP) to a computer running OMNeT ++, which supports an IP network topology created inside the simulator. In this way a complete network of devices, both simulated and physical, is created and can be used to collect statistical results of its performance, namely within OMNeT ++. We had because of receiving packets on average 64.4%, taking about 1.20 seconds for the transmission of each packet. We believe that the inefficiencies may have been due to both the bad contact of the components and the inefficiency of the designed code.
