How to Install
Requirements
IoDSim is developed as an extension of OMNeT++ (version 5.6.2) integrated with INET Framework (version 4.2.5). Hence, it is necessary to previously install these two tools.
Installing IoDSim
With OMNeT++ and INET previously installed, you just need to insert the IoDSim main directory as a subdirectory of INET framework. Thus, it will works as an INET extension.
Considering the OMNeT++ path tree, IoDSim must be inserted in the following path: [OMNeT++ root directory]/samples/inet/src/inet/. It must be inserted as the Figure shows below.

After, you just need to compile the INET framework and you are ready to use IoDSim!
