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