“…However, without breaking the current connection to the AP and establishing a new connection to the new AP, there is no way of accessing this information directly. 5 Candidate Access Router Protocol (CARD) [57] has been developed for the purpose of gathering information from the neighboring environment. CARD functions in IP layer and provides functionalities for gathering interface selection related information from the neighboring ARs.…”

This dissertation discusses mobility management in IP based wireless environments. Mobility management can include both handovers within one technology and selection of access technology in a heterogeneous overlapping environment. IETF has standardized Mobile IP and its IPv6 version for handling mobility management in the IP networks. Even though Mobile IPv6 handles mobility in an application transparent way, several unresolved problems remain. This dissertation focuses on minimizing the Mobile IPv6 handover delays and interface selection in heterogeneous wireless environments.An enhancement called Flow-based Fast Handover for Mobile IPv6 is presented for speeding up the Mobile IPv6 address registration phase. The address registration phase, and thus also packet loss, can be notably decreased. More importantly, the delay is not dependent on the distance of the Corresponding Nodes as is the case with Mobile IPv6. In addition, mechanisms to control Mobile IPv6 handovers to offer the users and applications a best access were researched. Real time information about the link status and quality as well as user preferences are taken into account in the interface selection. The objective is to offer an Always Best Connected access to the user, and seamless handovers.

“…[10,11,12,13,14] study the MIP application for specific network interworking and integration, providing a similar conclusion: the MIP approach may not be suitable for handover in all packet services, because of latency, delay, and packet loss. This approach suffers also from the triangle routing between networks if MIP does not support route optimization.…”

The original idea of Mobile IP (MIP) is to provide mobile users the ability to access the Internet anywhere, with an identical IP address. With rapid changes in both technology and the communication environment, wide bandwidth and low cost wireless LAN (WLAN) have emerged as a competitive choice not only for wireless high speed Internet access but also for wireless voice network access. To support mobility with Quality of Service (QoS), MIP has been found to be inefficient for both data and time sensitive services, such as Voiceover-IP (VoIP). In our paper, we first focus on the deficiencies of the MIP and other micro-mobility approaches found in the literature. We then propose an architecture for network layer mobility support, using always on high speed access and a network-based mobility manager, termed as network server or gateway. We believe that the proposed architecture obviates the need of MIP for IP mobility.
