Project Description
Castadiva is a test-bed solution that allows to generate wireless scenarios using low cost commercial-of-the-shelf devices combined with the power of Linux tools. Castadiva allows to generate a network topology, export it to real devices and obtain the results of the test. Can also generate different traffic between nodes, and integrate all more extended routing protocols in these networks. Using a cheap architecture based in two different networks: a wired network, called connection network, that connect the core with a group of wireless nodes; and a wireless network where the user makes its networks tests. We developed a group of tools for administration purpose, with a friendly user interaction to help the user to design the scenario of the network and define the desired traffic between all the nodes networks. All of these tools are developed with open source software. The main application, developed in Java, control all devices and generate links among their, creating a determined network topology. Also can order traffic generation between one source and address. The devices, called wireless nodes in our architecture, are autonomous and can generate and scan traffic individually. Each device combines some shell scripts with applications written in the C programming language. A test composed with autonomous devices approach to the real behavior of a network, and this is the point where Castadiva can help in networks researches. The main application only coordinate all nodes and translate to them the user's topology, but the test is executed only in the wireless nodes, without any extra application. Adding to this, Castadiva also can exports/imports the scenario and results to/from NS-2 simulator, giving the possibility of compare it with this powerful tool and making it compatible with the most extended simulator.
