Performance of Adaptive Hysteresis Vertical Handoff Scheme for Heterogeneous Mobile Communication Networks

This paper studies the performance of adaptive vertical handoff schemes for overlay WCDMA and wireless LAN (WLAN) heterogeneous networks. Simulation results show that the proposed adaptive hysteresis vertical handoff (AHVH) can increase lots of average data rate than the fixed hysteresis vertical handoff (FHVH) scheme. Moreover, the proposed AHVH scheme can reduce the ping-pong handoff rate as well .
