Abstract

The next generation Internet is expected to consist of different wireless networks with diverse performance. Given the complementary characteristics of 3G and WLAN, the combination of 3G and WLAN can achieve anywhere, anytime Internet access and bring benefits to both end users and service providers. For this purpose, an efficient vertical handoff (VHO) algorithm is needed to make intelligent handoff decision. In this paper, we analyze the signal strength model of mobile host (MH) during VHO and present a new Motion Model-based RSS Estimation (MMRE) algorithm. MMRE can adapt to the change of MH´s velocity and improve handoff efficiency. We have evaluated MMRE´s feasibility and effectiveness in simulations and compared its performance with existing handoff decision algorithms.
