This document specifies a mechanism that enhances Proxy Mobile IPv6 protocol signaling to support the creation of a transient binding cache entry that is used to optimize the performance of dual radio handover, as well as single radio handover. This mechanism is applicable to the mobile node’s inter-MAG (Mobility Access Gateway) handover while using a single interface or different interfaces. T...

Mobile IPv6 runs high risk of being attacked by IP spoofing due to the introduction of mobility and route optimization. In this paper, an authentic IP address validation scheme is proposed to protect mobile nodes in Mobile IPv6 against IP spoofing attack. The mobile nodes’ historical traffic information is leveraged to validate the authenticity of its claimed home address in the scheme. Compare...

⎯ This paper describes implementation details and performance comparison of route optimization for Proxy Mobile IPv6 (PMIPv6). The implementation details presented in the paper leverages route optimization mechanism defined in [5], which is based on Mobile IPv6 and extends the procedures in order to apply for PMIPv6. We also present the analytical performance comparison of route optimization sc...

Mobile ad-hoc networks are infrastructure-free, highly dynamic wireless networks, where central administration or configuration by the user is impractical. The Internet Protocol IPv6 defines mechanisms to autoconfigure interfaces of nodes in wired networks in a distributed manner. In this paper, the applicability of IPv6 Stateless Address Autoconfiguration and IPv6 Neighbor Discovery Protocol t...

In this paper, we propose an adaptive mobility management scheme for minimizing signaling costs in Hierarchical Mobile IPv6 (HMIPv6) networks. In our proposal, if the mobile node’s mobility is not local, the mobile node sends location update messages to correspondent nodes in the same way as Mobile IPv6 (MIPv6). After the creation of a spatial locality of the mobile node’s movement, the mobile ...

This paper addresses the problem of Local Mobility Management (LMM) for Mobile IPv6. First, the analysis on the conformance of the Hierarchical Mobile IPv6 (HMIPv6) to the fundamental LMM Requirements set out in the Internet Engineering Task Force (IETF) Internet Drafts, is carried out. This paper then describes three of our proposed solutions for LMM namely, “Route Tracing”, “En-Route Local Mo...

Mobile IPv6 (MIPv6) is protocol for handling routing of IPv6 packets to mobile nodes that have moved away from their home network. However, in MIPv6, the handover process reveals numerous problems manifested by a time-consuming network layer based movement detection and latency in configuring a new care-of address, with confirmation scheme called duplicate address detection (DAD). To reduce the...

Internet applications over the becoming standard IPv6 network have been increased significantly. Together with the rapid growth of mobile devices, a secure wireless IPv6 environment is needed. Current security methods, including EAP, 802.1x, Radius, etc., are still inadequate. In this paper, we study the security issues of IPv6, and its threats in the wireless environment, and propose an AAA (A...

The Next-Generation Wireless Networks (NGWNs) are believed to exhibit a heterogeneous environment which imposes various challenges, among them Mobility Management is most crucial. The FMIPv6 protocol has been standardized by IETF to address certain shortcomings of the baseline Mobile IPv6. However, it does not directly support vertical handovers. Therefore, research is still going on to develop...

connected hosts reduce this effectiveness, as do many web applications that demand multiple ports. NAT also introduces further complications (Box B). Nevertheless, many mobile networks employ NAT today, and more will do so in the future. While NAT was devised as a shortterm solution, the IETF defined the next version of IP, IPv6, as the long-term solution for the address shortage. IPv6 has nume...
