Using android platformin vertical handoff research

Massive use of wireless networks and the high rate penetration of mobile deviceshave raised several challenges to developers. One of the research problems of the data wireless networks is the so-called vertical handoff, and a great number of vertical handoff algorithms (VHA) that have been proposed. Most of these algorithms have been tested in simulated environments using simulation tools (e.g. NS-2, OMNeT++, NCTUNs), but only a few algorithms have been tested in a real environment. This paper presents a VHA controlled from a mobile phone and a software prototype for Android platform. One of the goals of our research was to validate the potential of Android´s platforms as a tool for research in the topic of controlled vertical handoff from mobile device (MCVHO).
