DEVELOPMENT OF A FRAMEWORK FOR HETEROGENEOUS WIRELESS NETWORKS

Abstract

ABSTRACT The world has been changed significantly by telecommunication technologies that help people to be better connected and more efficiently communicated. Today, telecommunication industry is migrating to the road map of technology which means a variety of technologies will be utilized together in order to maximize user experiences. One possibility is to use 3G technology when wireless LANs are not available and seamlessly switch between these technologies to provide improved and transparent connectivity. Currently there is no protocol to switch between heterogeneous networks. From the above mentioned a motivation was created to produce a framework to start from and to be used to find adequate clues to this issue. The aim of this thesis is to provide an overall picture of Seamless Mobility from high level, particularly critical technologies in Seamless Mobility –WLAN, GPRS and UMTS – were detailed illustrated from technical, market and regulation perspectives. The available interconnection scenario that can be used on the present infrastructure was proposed in form of framework, and the proposed solution was tested finally according to the available networks in the local market of operators, and performance result were presented and evaluated.
