Enhanced Mobile IP Protocol

Abstract

One of the most recent Internet challenges is to support transparent movement of people along with their computers, data and most of all applications. Therefore, Mobile IP has been developed to provide Internet mobility services. This paper aims at enhancing the IETF Mobile IP standard. The model developed in this paper suggests a new caching mechanism, which is based on the Mobile Information Server (MIS). Actually, the MIS is designed to be part of the border router of any network that supports mobility services. Moreover, the paper suggests a peering technique by which information about mobiles hosts could be shared among different MISs. All the design issues including model components as well as mechanisms for caching and peering are described in details. The simulation results show that the proposed design provides improved performance and better bandwidth utilization. The suggested architecture provides other qualitative advantages such as scalability and transparency.

“…The initial proposed MIP was host based. Its'deployment required MN's kernel modification and introduced inefficient data forwarding, called triangle problem, that hindered its applicability in large deployments (Esmat, 2000;Mikhail, 2001;Weyland, 2002). Later, MIPv6 was introduced in RFC 3375 as host-based mobility protocol for supporting MNs' global mobility (Johnson, 2004).…”
