The functionalities of the next generation Internet protocol, IPv6, have become increasingly interesting due to the current merging of the traditional cellular mobile communications and the traditional data-communications into the future wireless systems, as e.g., UMTS. IPv6 provides several enhanced functionalities requested for the future mobile systems. In this article the largest advantages...

This document describes the requirements and desired properties of Network Mobility (NEMO) Route Optimization techniques for use in global-networked communications systems for aeronautics and space exploration. Substantial input to these requirements was given by aeronautical communications experts outside the IETF, including members of the International Civil Aviation Organization (ICAO) and o...

---International Engineering Task Force (IETF) proposed MIPv6 and HMIPv6 both mobility management solutions to support the IP mobility. Although HMIPv6 is an extension of MIPv6 still there is handover latency and packet loss in HMIPv6.In this paper a scheme is presented that supports a fast handover efficiently in hierarchical mobile IPv6 networks (HMIPv6). In HMIPv6 when a mobile node (MN) mov...

For extending the lifetime of a mobility session, the Proxy Mobile IPv6 specification requires the mobile access gateway to send a Proxy Binding Update message to the local mobility anchor on a per-session basis. In the absence of signaling semantics for performing operations with group-specific scope, this results in a significant amount of signaling traffic on a periodic basis between a given...

Service discovery is an essential component for distributed mobile applications in vehicular communication systems. While there have been numerous service discovery protocols, applications for vehicular communication systems pose additional requirements: discover services according to geographical position inside dynamic mobile environments. In this article, we propose a geographical location a...

We report from experiments with wireless and mobile computing at the University of Oslo, NORWAY. We have established a wireless Experimental Metropolitan Area Network (WEMAN), based on Mobile IPv6 for mobility and IEEE 802.11 technology for wireless links and access.. WEMAN is a wireless extension of the IPv6 based Internet 2 in Norway, and enables flexible access for nomadic and mobile users. ...

Mobile IPv6 is the IETF proposition to support host mobility in the Internet. It provides routing optimization for packets sent to the mobile node at the expense of signaling messages that are periodically sent to the correspondent of the mobile node. We propose using XCAST, a multicast technique best designed for small groups, as a means to decrease this signaling. XCAST records the addresses ...

This paper addresses the identifier ownership problem. It does so by using characteristics of Statistic Uniqueness and Cryptographic Verifiability (SUCV) of certain entities which this document calls SUCV Identifiers and Addresses. Their characteristics allow them to severely limit certain classes of denial of service attacks and hijacking attacks. SUCV addresses are particularly applicable to ...

In this paper an analytical model is presented in order to provide useful insight into the performance behaviour of Mobile IPv6 in the context of a binding lifetime setting. By using this model, the optimal binding lifetime can be estimated in terms of a user mobility, traffic workload, and network structure. An algorithm for dynamically setting the binding lifetime in Mobile IPv6 networks is p...
