Paper Title:

On seamless intergration of Wireless Networks 

Abstract: 

Low tier wireless systems such as Wireless LAN (WLAN) support bandwidth-intensive applications with less mobility support. On the other hand, high tier wireless systems such as GPRS and UMTS/GSM provide users an increased range of connectivity with less bandwidth. Packet-data services are an important growth area for Wireless Wide Area Networks (WWANs). WLAN is seen as an important medium for offering services that couldn't otherwise satisfactorily be offered with WWAN technology alone. While several approaches have been proposed in literature for improving the performance of wireless data networks, a recent class of approaches has focused on improving the underlying wireless network model itself. WLAN must be able to handle session continuity just as well as WWAN has done for voice over the years. This paper looks into a seamless integration environment, which consist of various heterogeneous networks like Bluetooth Scatternets (WPAN), 802.11 networks (WLAN), and GSM/UMTS (!

WWAN/WMAN). It should be possible to reach a user's device regardless of the network to which it is attached. Ultimately, devices with various enabling technologies can talk to each other and also switch between technologies according to desired Quality of Service (QOS) requirement, security and other factors like power consumption, required bit rate etc., while maintaining session continuity across the two or more access types. This paper considers roaming and handover between these access types. The problems and challenges faced in a WLAN environment are outlined and multi-tier wireless cell architecture is introduced.
