Title

A Smart Decision Model for Vertical Handoff

Abstract

As mobile computing increases in prevalence and popularity, it is becoming increasingly important to have a vertical handoff solution, which can perform a vertical handoff seamlessly and smartly. In this paper, we propose a Smart Decision Model to decide the “best” network interface and “best” time moment to handoff. A score function is utilized in the model to make the smart decision based on various factors, such as the properties of available network interfaces, the system information, and the user preferences. A USHA based testbed is created to evaluate this model in various scenarios, and the results show that our model is feasible and helpful in mobile computing scenarios. Additionally, this model is simple and also applicable to other vertical handoff approaches.
