Mobile IP: state of the art report

Due to roaming, a mobile device may change its network attachment each time it moves to a new link. This might cause a disruption for the Internet data packets that have to reach the mobile node. Mobile IP is a protocol, developed by the Mobile IP Internet Engineering Task Force (IETF) working group, that is able to inform the network about this change in network attachment such that the Internet data packets will be delivered in a seamless way to the new point of attachment. This document presents current developments and research activities in the Mobile IP area

Mobile IP

The Internet is growing exponentially, both in the amount of traffic carried, and in the amount of hosts connected. IP technology is becoming more and more important, in company networks (Intranets), and also in the core networks for the next generation mobile networks. Further, wireless access to IP networks is becoming mature (e.g., IEEE 802.11 networks, Irda, Bluetooth). At the same time, the existing generation of mobile (cellular) networks is evolving from voice services to networks with a rich mixture of services (e.g., GPRS and 3rd generation networks). These developments demand for mobility in IP-based networks. A first solution to this problem has been proposed as Mobile IP. This solution makes use of Home Agents and Foreign Agents to allow mobile hosts to move freely between subnetworks while communicating.\ud \ud The tutorial will describe and explain the approaches taken to provide mobility for hosts in the Internet and IP-based networks. The tutorial will start with expanding on the need for Mobile IP. It will briefly explain the main Internet principles relevant to Mobile IP. The problems Mobile IP is trying to solve will be explained. After an overview of the general operation of Mobile IP, the principal mechanisms will be discussed in more detail. The tutorial will describe the operation of advertising care-of addresses, mobile host registration, tunneling, and proxy- and gratuitous ARP. Special attention will be paid to the main problems related to Mobile IP, such as triangle routing and smooth hand-off. The tutorial will finally explain how mobility can be supported in IPv6.\u

Secure and privacy-aware proxy mobile IPv6 protocol for vehicle-to-grid networks

Vehicle-to-Grid (V2G) networks have emerged as a new communication paradigm between Electric Vehicles (EVs) and the Smart Grid (SG). In order to ensure seamless communications between mobile EVs and the electric vehicle supply equipment, the support of ubiquitous and transparent mobile IP communications is essential in V2G networks. However, enabling mobile IP communications raises real concerns about the possibility of tracking the locations of connected EVs through their mobile IP addresses. In this paper, we employ certificate-less public key cryptography in synergy with the restrictive partially blind signature technique to construct a secure and privacy-aware proxy mobile IPv6 (SP-PMIPv6) protocol for V2G networks. SP-PMIPv6 achieves low authentication latency while protecting the identity and location privacy of the mobile EV. We evaluate the SP-PMIPv6 protocol in terms of its authentication overhead and the information-theoretic uncertainty derived by the mutual information metric to show the high level of achieved anonymity

Secure Mobile IP with HIP Style Handshaking and Readdressing

Mobile IP allows the mobile node roaming into a new IP network without losing its connection with its peer. Mobile IPv6 is using Mobile IP with Route Optimizationto improve performance by avoiding the triangle routing and adopting Return Routability as a secure process for binding update. Host Identity Protocol (HIP) is an experimental security protocol which provides mobility management and multi-homing by its new namespace. Its architecture is similar to that of Mobile IP with Route Optimization. In this paper, we have introduced a Secure Mobile IP with HIP Style Handshaking and Readdressing (SMIP), which has stronger security, better performance and lower binding cost in binding update process compared with Mobile IPv6. The dependence of home agent in the new scheme is also shown dramatically decreased. The initiated scheme integrated the primary features of two completely different mobility management solutions and has set up a migration path from mobile-IP based solution to a public-key based solution in mobile IP network

Security against DoS attack in mobile IP communication

As like as wired communication and mobile ad hoc networking, mobile IP communication is also vulnerable to different kinds of attack. Among different kinds of attack Denial-of-Service (DoS) is a great threat for mobile IP communication. In this paper we proposed to imply a lightweight packet filtering technique in different domains and base stations of mobile IP communication. If there is any packet containing spoofed IP address created byDoS attackers, our scheme can detect and then filters the suspected packets. We evaluated the performance of our proposed scheme using ns-2. The results indicate that our proposed scheme can significantly reduce the effect of DoS attacks and improves performance of mobile IP communication

Mobiili-IP

Tässä työssä tutustuttiin mobiili-IP:hen. Mobiili-IP tarkoittaa sitä, että sama IP-osoite on käytössä kotiverkkoon, oli käyttäjän yhteys tai sijainti sitten mikä tahansa. Tavoitteena oli tuoda esille mitä mobiili-IP tarkoittaa ja mitkä ovat sen eri kom-ponentit. Tässä työssä oli myös esimerkkinä mobiili-IP:n käyttöönotto Cisco 1841-reitittimellä. Eri komennot esitettiin listauksena ja lopussa oli selitys mitä tehtiin. Opinnäytetyö aloitettiin keräämällä tietoja internetistä ja Ciscon julkaisemista kirjoi-ta. Näistä sitten poimittiin mobiili-IP:n kannalta oleelliset tiedot.This thesis explored Mobile IP. Mobile-IP means that the same IP address is used on the home network, despite the location or the connection of the user. The aim was to bring out what Mobile-IP is and what its various components are. This the-sis used as an example adopting Mobile IP on Cisco 1841 router. The various commands were presented as a list and what was done was explained at the end. This thesis began by collecting information from the Internet, and from Cisco's publications. The essential information for Mobile-IP was then gathered from these sources

On the security of the Mobile IP protocol family

The Internet Engineering Task Force (IETF) has worked on\ud network layer mobility for more than 10 years and a number\ud of RFCs are available by now. Although the IETF mobility\ud protocols are not present in the Internet infrastructure as of\ud today, deployment seems to be imminent since a number\ud of organizations, including 3GPP, 3GPP2 and Wimax, have\ud realized the need to incorporate these protocols into their architectures.\ud Deployment scenarios reach from mobility support\ud within the network of a single provider to mobility support\ud between different providers and technologies. Current Wimax\ud specifications, for example, already support Mobile IPv4,\ud Proxy Mobile IPv4 and Mobile IPv6. Future specifications will\ud also support Proxy Mobile IPv6. Upcoming specifications in\ud the 3GPP Evolved Packet Core (EPC) will include the use of\ud Mobile IPv4, Dual Stack MIPv6 and Proxy Mobile IPv6 for\ud interworking between 3GPP and non 3GPP networks.\ud This paper provides an overview on the state-of-the-art\ud in IETF mobility protocols as they are being considered by\ud standardization organizations outside the IETF and focusing\ud on security aspects
