Abstract

Mobile computing has become an important area of computer networking and is expected to play a fundamental role in the ubiquitous access of Internet resources in the future. In recent years, we have seen increasing demand from end-users to access network resources from anywhere and at anytime from all kinds of devices. A greater degree of connectivity is almost becoming mandatory in todays business world. In addition, mobility of end-users is placing further requirements on network systems and protocols to provide uninterrupted services. Mobile network protocol such as Mobile IPv4 has emerged as one of the promising solutions capable of providing uninterrupted connectivity. It allows the users to roam beyond their home network while still maintain their own home IP address. Similarly, Mobile IPv6 is the protocol that deals with the mobility for the IPv6 nodes. This protocol allows an IPv6 node to be mobile, and arbitrarily change its location on the IPv6 Internet while still maintaining its existing connections.We have done a study of the MobileIP technology, and the components that support this technology. We investigated the impact of mobility on the performance of voice and video conferencing applications over Mobile IPv4 and Mobile IPv6. Through this paper, we have made an attempt to identify the strengths and weaknesses of the two mobility protocols and discover which protocol leads the future generation Internet.This paper is organized as follows. The first part briefly overviews the two mobility protocols (Mobile IPv4 and IPv6). The second part describes the basic scenarios of the network model that are required to conduct such evaluation, followed by the results of the simulation. Final part describes the conclusion of our study.
