This paper describes a new network architecture called LINA (Location Independent Network Architecture) that supports node mobility. It also describes a new protocol called LIN6 that is based on LINA. LIN6 is fully compatible with IPv6 and free from the problems of Mobile IPv6. Our prototype implementation of LIN6 has a much lower processing overhead in comparison with conventional IPv6.

Future internetworks will include large numbers of portable devices moving among small, wireless cells. In order to support real-time applications, users demand seamless mobility and Quality-of-Service (QoS) provisioning. One approach towards a more flexible, customizable and scalable mobility architecture that also reduces signaling load and handoff latency results from the introduction of mic...

USAGI Project [8] has improved Linux IPv6 [1] stack. IPv6 IPsec is one of the products of our efforts. Linux IPsec [6] stack is implemented based on XFRM architecture which is introduced in linux-2.5. We design and implement Mobile IPv6 (MIPv6) [4] Stack on the architecture. MIPv6 uses IPsec for its secure signaling. Accordingly IPv6 IPsec and MIPv6 closely cooperate each other. In this paper w...

This document lists security threats related to IPv6 multihoming. Multihoming can introduce new opportunities to redirect packets to different, unintended IP addresses. The intent is to look at how IPv6 multihoming solutions might make the Internet less secure; we examine threats that are inherent to all IPv6 multihoming solutions rather than study any specific proposed solution. The threats in...

Mobility management protocols play a vital role during mobile node transmission. That’s why IETF NETLMM working group has recently presented a new approach, i-e, Proxy Mobile IPv6 (PMIPv6) which is a network-based mobility management protocol. But, PMIPv6 still suffers from the long authentication latency during the handover process. In order to improve the performance of Proxy Mobile IPv6, Hyu...

A seamless handover scheme with low latency and low packet loss is an important issue to maintain end-to-end TCP performance of mobile users. Several solutions have been proposed as extensions of Mobile IPv6 to improve the handover performance of mobility, each solution has its own advantages and disadvantages, and therefore, an standardized handover mechanism is not accepted yet. In this paper...

In this paper we present a scheme that enables a mobile user to perform a ”QoS-conditionalized” handoff when moving to an overlapping area in Mobile IPv6. The idea is to use a QoS hop-by-hop option piggybacked in the binding messages for QoS signaling and conditionalize a handoff upon the availability of sufficient resources along the new transmission path. Our scheme builds upon the hierarchic...
