摘要

研究了覆盖WCDMA和WLAN异构网络的自适应垂直切换方案的性能。仿真结果表明，所提出的自适应迟滞垂直切换方案比固定迟滞垂直切换方案能提高大量的平均数据速率。此外，提出的自适应迟滞垂直切换方案还可以降低乒乓切换率。

Performance of Adaptive Vertical Handoff in Heterogeneous Networks of WLAN and WCDMA Systems

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.
