Network Layer: Its Architecture, Survey and Network System

IEEE Personal Communications, 2000

Wireless access to Internet services will become typical, rather than the exception as it is today. Such a vision presents great demands on mobile networks. Mobile IP represents a simple and scalable global mobility solution but lacks the support for fast handoff control and paging found in cellular telephony networks. In contrast, second- and third-generation cellular systems offer seamless mobility support but are built on complex and costly connection-oriented networking infrastructure that lacks the inherent flexibility, robustness, and scalability found in IP networks. In this article we present cellular IP, a micro-mobility protocol that provides seamless mobility support in limited geographical areas. Cellular IP, which incorporates a number of important cellular system design principles such as paging in support of passive connectivity, is built on a foundation of IP forwarding, minimal signaling, and soft-state location management. We discuss the design, implementation, and evaluation of a cellular IP testbed developed at Columbia University over the past several years. Built on a simple, low-cost, plug-and-play systems paradigm, cellular IP software enables the construction of arbitrary-sized access networks scaling from picocellular to metropolitan area networks

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.

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.

This paper speci es a new mobile host protocol, Mobile IP (MIP), to allow packets between mobile hosts or mobile networks and other hosts (including xed hosts) to be delivered transparently along close to optimal routes. MIP introduces a new IP option to encode MIP routing data into IP packets. Only a small amount of overhead is introduced to each packet and no changes are needed to layers above the IP layer.

In this paper we discuss several issues with the present usage model for Mobile-IP that tend to limit its deployability and suggest solutions to most of these practical deficiencies. In particular, we conclude that the Mobile IP protocols and implementations should operate with any number of Home Agents. That is, from none to many.

In the current Cellular IP architecture, only one gateway serves the entire CIP network. So, the gateway is single point of failure for all the mobile hosts who rely on it to be connected to the Internet. Cellular IP requires that a mobile host be using exactly one gateway to the Internet backbone with Mobile IP at a time. When multiply gateways are used in a cellular IP network, the optimal design for the multiple domains is needed. The cellular IP protocol provides better performance for hand-off than other protocol using micromobility. A set of base station cluster together on the same cellular IP network. This kind of domain base network is superior to mobile IP in support of routing optimization and QoS. Experiment were conduct to explore load our protocol and survey the packet loss. This result so that the load of control packet is negligible for cellular IP and the number of lost packet can be successfully reduced. This thesis developed to design cellular IP architecture and fault detection mechanism and recover the protocol of cellular IP.

Among the characteristics of future wireless networks is the desire to support a wide range of wireless users and a diverse set of services from many different types of networks. One of the most often referenced networking protocols for diverse wireless and mobile networking is Mobile IP. Although recent focus has been on developing a micro-mobility architecture for Mobile IP, an emerging need is to enhance the unifying performance of Mobile IP by using a crosslayer, cross-technology, approach to protocol design, in order to serve a wide variety of users, services and networks. This paper provides a survey of recently proposed performance enhancements for Mobile IP and discusses the impact on network-level performance. After a review of the Mobile IP architecture, recent research on reducing handoff latency is discussed, including the use of layer 2 hints. Then, location registration is explored, including new techniques for authentication of mobile users. Finally, an overview of performance analysis models is provided to show the most recent approaches to determining the impact of mobility on a given network.

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.

A Review on Mobile Internet Protocol (Mobile IP), 2019

Mobile IP is a new internet protocol as compared to the already existing networking protocols used for embracing the connectivity and communication. Mobile computing devices have taken over from the yester years and the hosts (users) demanding connectivity is not stationary as well. There was no such protocol before Mobile IP which would deal with the issues like these. Mobile IP serves the need of the population to connect to the internet and have a uniform connection irrespective of lactation. This paper deals with the background, operation mechanisms, issues along with some of their solutions, advantages of Mobile IP which over weights the disadvantages and finally the conclusion pertaining to the Mobile IP.
