my team and I are working in a project based on the drone Parrot API.
We are trying to find an api to write a small program which can scan the wireless network and selects
No API but you can try: Excecute iwconfig from a java application
You can also try http://kosmosisland.com/island/david/kosmos-island-wireless.php . They have a Java Applet (with source) that monitors the Wireless Link. You can see how they did it.
