The rapid growth of wireless technologies and the increasing demand for new services (www, e-mail, VoIP, multimedia streaming) has caused the necessity to make package routing services of IP networks available to users using wireless devices. However, user mobility causes additional administration complexity, since the initial design of IP networks, did not include provision for mobile nodes. The main objective of the present dissertation is the study of the impacts of the heterogeneous environment in Quality of Service (QoS) parameters of wireless networks. Specifically, the general concept of mobility management for heterogeneous networks is described and two wireless networks, a Universal Mobile Telecommunications System (UMTS) and a Wireless Local Area Network (WLAN), are combined in order the performance of this heterogeneous wireless network to be examined. A heterogeneous network is a network connecting computers and other devices with different operating systems and/or protocols. The word heterogeneous network is also used in wireless networks using different access technologies. For example, a wireless network which provides a service through a wireless LAN and is able to maintain the service when switching to a cellular network is called a wireless heterogeneous network. We will be developed the handoff’s methods and will be reported particularly, in location management, in handoff management and more specifically in horizontal handoff and in vertical handoff.
