In-home networking is becoming a reality. New multimedia applications envisaged for in-home networks require data rates of hundreds of Mbps. In order to provision these applications, wireless networks should provide the user with high speed transmission using short-range Gbps wireless technology. With its unlicensed 5 GHz of spectrum, 60 GHz is envisaged for indoor broadband wireless networks. However, handoff in 60 GHz network occurs with a high rate due to the smaller cell size while using 60 GHz. Thus, the resources in such network vary frequently. So providing QoS guarantees in this network is more difficult than in traditional wireless networks. In this paper, we propose the handoff scheme using movement prediction. The prediction model is based on Hidden Markov Model. The simulation results show that the proposed scheme performs well compared to the two schemes in literature in terms of the call dropping probability and the call blocking probability.
