Mobility Management Using the IP Protocol

A typical Internet protocol (IP)could not address the mobility of nodes and was only designed for fixed networks where the nodes were improbable to move from one location to other. An ever-increasing dependence on network computation makes the use of portable and handy devices,inevitable. Mobile IP protocol architecture was developed tomeet such needs and support mobility. Mobile IPlets the roving nodes to establish an uninterrupted connection towards internet without altering the IP address whilemoving to another network.However, Mobile IP goes through several issues like ingress filtering, triangle routing, handoff and Quality of service problems etc. In this paper we discuss few of those with their possible solutions. That resolves these problems, reduce the unnecessary load from the network and enhance the efficiency. Some security threats on mobile and their solutions are also focused to secure the communicationduring mobility.

We consider the problem of providing network access to hosts whose physical location clianges with time. Such hosts cannot depend on traditional forms of network connectivity and routing because their location, and hence the route to reach them, cannot be deduced from their network address. In this paper, we explore the concept of providing continuous network access to mobile computers, and present a set of IP-based protocols that achieve that goal.

With the ever increasing use of portable and hand held devices for voice and data transfer, there is a growing expectation to access information anytime, anywhere. Today there are different technologies providing access to voice, data, and video. These need to be converged in all Internet protocol (IP) based network. Next generation telecom networks will be having convergence of voice and data traffic and use of IP based mobility solutions. Mobile IP is a TCP/IP-based protocol that has been standardized by the IETF (Internet Engineering Task Force) for supporting mobility. Mobile IP is part of both IPv4 and IPv6 standards. Mobile IP works at network layer (layer 3), influencing the routing of packets and can easily handle mobility among different media. This chapter discusses different technical operations involved in Mobile IPv4 and Mobile IPv6 and compares them.

Mobility management in the wireless domain is a challenging issue for the next generation networks. Frequent change of network requires a new IP address to route packets from one host to another. It is done by sending the mobile node (MN) binding update to the Home Agent (HA) when the Care of address (CoA) gets changed. This registration requires large number of location updates, excessive signaling overhead and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) protocol using the concept of hierarchy of Foreign Agent and the Gateway Foreign Agent /Mobility Anchor point to localize the registration information. This article presents an overview of set of HMIP based mobility protocols such as HMIP, PHMIP, RHMIP, DHMIP, FFHMIP, MIFA etc. that will play an important role in IP based mobility management.

Mobility management in wireless Internet environment has become a vital issue. To handle the mobility in Internet the mostly used protocol is Mobile IPv4. In Mobile IPv4 protocol the two new entities are introduced. The entities are Home Agent (HA) and Foreign Agent (FA). The HA resides in home network of mobile node and it is used to track the current position of mobile node. The foreign agent resides in the foreign network which maintains the link with the home network of the mobile node on behalf of mobile node. But due to the limitation of address capability, triangle delay problem of Mobile IPv4 a new protocol is proposed which is known as Mobile IPv6. Mobile IPv6 [2] protocol enhances the communication system in mobile environment of Internet. But the major drawback of Mobile IPv6 is that it suffers from handover latency and packet loss problem. A new scheme is proposed in this paper to remove the limitations of Mobile IPv6. The newly proposed scheme uses the probability mecha...

We point out the different performance problems that need to be addressed when considering mobility in IP networks. We also define the reference architecture and present a framework to classify the different solutions for mobility management in IP networks. The performance of the major candidate micro-mobility solutions is evaluated for both real-time (UDP) and data (TCP) traffic through simulation and by means of an analytical model.

The recent advances in wireless communication technology and the unprecedented growth of the Internet have paved the way for wireless networking and IP mobility. Mobile Internet protocol has been designed within the IETF to support the mobility of users who wish to connect to the Internet and maintain communications as they move from place to place. This study describes and summarizes the current Internet draft for mobile IP (MIPv4) with its major components: agent discovery, registration and tunneling. In addition, we outline the available encapsulation techniques and route optimization procedure. In the end, we describe the design of the new protocol for transparent routing of IPv6 packets to mobile IPv6 nodes operating in the Internet.

With the introduction of a newer generation of wireless devices and technologies, the need for an efficient architecture for IP mobility is becoming more apparent. Several architectures have been proposed to support IP mobility. Most studies, however, show that current architectures, in general, fall short from satisfying the performance requirements for wireless applications, mainly audio. Other studies have shown performance improvement by using multicast to reduce latency and packet loss during handoff. In this study, we propose a multicast-based architecture to support IP mobility. We evaluate our approach through simulation, and we compare it to mainstream approaches for IP mobility, mainly, the Mobile IP protocol. Comparison is performed according to the required performance criteria, such as smooth handoff and efficient routing. Our simulation results show significant improvement for the proposed architecture. On average, basic Mobile IP consumes almost twice as much network bandwidth, and experiences more than twice as much end-to-end and handoff delays, as does our proposed architecture. Furthermore, we propose an extension to Mobile IP to support our architecture with minimal modification.
