In this paper, channel allocation scheme is studied for overlay wireless networks to optimize connection-level QoS. The contributions of our work are threefold. First, channel allocation scheme using both horizontal channel borrowing and vertical channel borrowing is presented and analyzed. Channel borrowing is restricted within handoff requests, and only(More)
