The main feature of the next generation wireless communication systems is the ability to establish ubiquitous and seamless access to various Radio Access Technologies (RATs) and standards. For this reason the integration of cellular and Wireless Local Area Networks (WLANs) and performance evaluation of the interaction between these technologies is now an important research area. Modeling such systems for performance evaluation is essential to improve the architecture according to the Quality of Service (QoS) requirements and performance characteristics. In this paper, an analytical model for performance evaluation of an integrated cellular network and a WLAN is considered. WLAN is deployed inside of the cellular network to support handoffs between cellular networks with higher bandwidth.
