This document describes the GPS based handover modul, which was developed by the Mobil Innovation Centre, and the description of the peer-to-peer sub-modul, which improves the effeciency of the above--mentioned modul.

First of all, in Section 1, I introduce the initial and the supplemented system briefly, not concentrating on the code level description. Thereafter in Section 2 I expound the used network architecture with its advantages and disadvantages. Section 3 contains all the used message types, and a few examples about the operation of the modul. Some flow charts, are trying to help the Reader understanding how the whole sub-modul works. After being aware of how the DBU works, in Section 4 I explain, why I have chosen JAVA as the language of the implementation. However this thesis is not written with the aim of describing the whole implementation in the code level, but I consider it important to give a general knowledge about the classes and methods of the sub-modul, and a few SQL operations. In Section 5 I introduce the installation of the modul on Ubuntu systems, and finally I present the results of the testing process.
