Abstract
Mobile IP is the Internet Engineering Task Force (IETF) proposal to cater for All-Internet Protocol (All-IP) mobility. It forms the backbone for next generation Wireless Internet Technology to provide uninterrupted network service while on the move. Our paper conducts a performance study of the various Mobile Internet Protocol version 6 (IPv6) protocols such as Simple Mobile IPv6, Hierarchical Mobile IPv6, Fast handover Mobile IPv6, their combination and Simultaneous Bindings Mobile IPv6. The paper benchmarks the protocol variations against the standard Mobile IPv6 protocol, by studying them under Quality of Service (QoS) parameters. We propose an evaluation model containing 5 mobile nodes and then gradually (5 nodes per stage) increasing the mobile nodes to 50. The proposed network model is then simulated in an open source simulator NS-2. This paper goes further to propose the most suitable variation of the protocol to use and the challenges faced in deployment.
Highlights
The Internet has been ever growing in terms of its services
The initiation of forwarding of packets between Previous Access Router (PAR) and New Access Router (NAR) is based on an ‘anticipated timing interval’, that is, the network anticipates the time at which the mobile node is likely to handoff
One scenario that we propose for initiating the usage is the cellular phone network
Summary
The Internet has been ever growing in terms of its services. As new features are included in the Internet, new users are added to exploit them. In Mobile IP, the mobile node sends binding update to the home agent and the correspondent nodes each time it changes its point of attachment regardless of the magnitude of the movement. This procedure causes registration delay and packet loss. The initiation of forwarding of packets between PAR and NAR is based on an ‘anticipated timing interval’, that is, the network anticipates the time at which the mobile node is likely to handoff This kind of interval is very difficult to generalize and forwarding too early or too late will result in huge packet losses. Performance metrics: Performance comparison quantitatively evaluates the variations of the mobile IPv6 protocol variations based on the following parameters:
