In this work I firstly present an overview on current wireless technology and network mobility focusing on challenges and issues which arise when mobile nodes migrate among different access networks, while employing real-time communications and services. In literature many solutions propose different methods and architectures to enhance vertical handover, the process of transferring a network communication between two technologically different points of attachment. After an extensive review of such solutions this document describes my personal implementation of a fast vertical handover mechanism for Android smartphones. I also performed a reliability and performance comparison between the current Android system and my enhanced architecture which have both been tested in a scenario where vertical handover was taking place between WiFi and cellular network while the mobile node was using video streaming services. Results show the approach of my implementation to be promising, encouraging future works, some of which are suggested at the end of this dissertation together with concluding remarks.
