Abstract |
The next generation of wireless communications will be based on a heterogeneous infrastructure consisting different wireless and wired access systems where users will enjoy fast and seamless mobility and “anytime - anywhere” access to applications with least interruption and disruption of wireless connectivity .In this context, a strong need has been emerged to integrate WLAN with 3G mobile networks and design a hybrid architecture capable to suffice the needs of users with ubiquitous data services and seamless roaming .This paper addresses this need by introducing a vertical handoff algorithm for integrated UMTS-WLAN which uses signal strength as well as predefined threshold value to predict where and when the handover should occur, thus optimizing user throughput and network performance. |
