Introduction to Combined Smart Decision Model for Vertical Handoff

Abstract

The performance of handoff is one of the key issues for providing the quality of services in wireless technology. Different model have been proposed to reduce the handoff .In this paper, we propose a Combined Model to decide the “best” network interface and “best” time moment to handoff. We enhanced original score function using the dynamic weight factor to make the smart decision based on various factors, such as the link cost, charge consumption, data rate, signal strength and user availability. The proposed combined model performs better in terms of usage-cost and consumption. We have simulated our proposed model and found that it saves 22.26%, of the usage cost and 21.67% of the charge consumption compared to the original model.
