GatcomSUMO is a multi-platform application that facilitates the building of VANET simulations using the SUMO traffic simulator and the OMNeT++ network simulator. The tasks related to the generation of abstract or synthetic scenarios, the download and conversion of network scenarios based on real maps (e.g. from OpenStreetMap), the route creation process, and the vehicles mobility modelling are integrated in a user-friendly graphical interface. This tool performs the necessary actions by invoking the set of utilities included in SUMO, saving the user from typing complex command-line orders. GatcomSUMO visualizes the network and routes easily, and they are created in such a way to meet the requirements of the involved simulators, in particular OMNeT++, in order to avoid misunderstandings and runtime errors. ...

...How can we test some new drugs without using animals? These and many other problems are initially solved by using simulators. It is extremely expensive, and sometimes dangerous, to test initial ideas in a real environment. We must use simulators to achieve comfortable confidence levels before real tests. This way, we develop simulation models where entities, named sensors, collect environment data, process data, communicate, move around the space and a lot more. JSensor is a sensor network simulator implemented at Computer Science Department of Federal University of Ouro Preto (DECOM-UFOP), Brazil. ...

There is a need for realistic node topologies for simulating and testing wireless network protocols. The softare evoTopo is able to generate multiple different topologies based on a given reference example, typically from a real-world setup. Based on this an evolutionary algorithm evolves new topology files with equal parameters regarding node density, distribution homogeneity and network properties such as node degree distrbution. evoTopo can be used with any wireless network simulator that will accept a node position file of some form. The reference file must be given in .csv format listing the x- and y-coordinates of the nodes. evoTopo is written in Java and will run on Java 6 or higher. ...
