Fransisco Derridy J.P.R ABSTRACT

DESIGNING AND IMPLEMENTING MOBILE AD-HOC NETWORK BASED ON ANDROID SMARTPHONE FOR DYNAMIC INFRASTRUCTURE

By

Ir. Arko Djajadi, M.Sc., Ph.D, Advisor

SWISS GERMAN UNIVERISTY

The purpose of this thesis is to prevent an accident from happening by using mobile ad-hoc network in android smartphone. This thesis is an improvement from the previous project in communication system. Multi peers communication is needed to communicate in real world application, so the devices can communicate among each other. Implemented in Android based smartphones equipped with built-in WiFi Direct, the mobile ad-hoc network will enable information sharing about road condition and warning to other devices seamlessly so it can prevent accident. The system uses internal android sensor to read the environment and GPS to determine the position of the server and the clients. The system has been tested in road condition and can communicate between multiple devices and share warning signal successfully.

Keywords: Android, Communication System, WiFi Direct, Java.
