Micro-Mobile MPLS : Performance Analysis and Improvement with RSSI

In this paper we propose the method to decrease the numbers of losing packet while moving across the network by Received Signal Strength Indicator (RSSI) Technique using define appropriately signal strength between MN (Mobile Node) and FA (Foreign Agent). We use this technique to serve in Micro-Mobility MPLS for improvement sending packet. The simulation has improved the performance of Mobile MPLS by reducing losing packet

Mobile MPLS-TP - Support the mobility of terminal devices

MPLS architecture for transport networks play the significant role in the development of next generation networks, in particular with regard to the guarantee of continuity of communications "end-to-end" through a variety of heterogeneous segments of the telecommunications network. The article presents the concept of Mobile MPLS-TP with the use of OAM channels to support the mobility of users and optimize "Handoff" procedure in a hierarchical network topology

A mobility architecture for IP networks and its realization over MPLS protocol

Orientador: Eleri CardozoTese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Elétrica e de ComputaçãoResumo: A próxima geração da telefonia celular, 4G, será totalmente baseada no protocolo IP. Para o usuário final, a expectativa é estar constantemente conectado à esta rede, no qual a característica fundamental será a mobilidade transparente do dispositivo móvel, entre as várias subredes que compõem um domínio administrativo. Esta tese tem por objetivo propor uma solução para o problema da mobilidade transparente do dispositivo móvel em redes IP. Como consequência, duas contribuições são alcançadas. A primeira é a especificação de uma arquitetura que permita localizar e rastrear o dispositivo móvel em um domínio administrativo, que seja independente da tecnologia de túneis utilizada na camada de rede. A segunda é a proposição de um método de rastreamento do dispositivo móvel em redes MPLS, preservando as especificações do protocolo MPLS. É mostrado também como este método foi integrado com a arquitetura previamente definida. Por fim, é descrita como essa proposta de rastreamento em redes MPLS foi implementada sobre o sistema operacional Linux e os testes realizados para avaliar, tanto a implementação desta proposta, quanto a sua integração com essa arquiteturaAbstract: The next generation of cellular telephony, 4G, is going to be totally based on the IP protocol. The end user expects to be constantly connected to this network, in which the key feature Will be the seamless mobility of the mobile device among the various subnets within an administrative domain. This thesis has as objective to propose a solution to the problem of seamless mobility of the mobile device in IP networks. As such, two contributions are achieved. The first one is the specification of an architecture able to locate and track the mobile device inside an administrative domain, being independent of the tunnel technology used in the network layer. The second one is the proposition of a method to track the mobile device inside a MPLS networks, keeping intact the specifications of the MPLS protocol. It is also shown how this method was integrated with the previously defined architecture. Finally, it is described how the proposed method to track mobile devices inside a MPLS network was implemented on the Linux operating system, and the tests performed in order to assess both the implementation of this proposal and its integration with this architectureDoutoradoEngenharia de ComputaçãoDoutor em Engenharia Elétric

Radio Communications

In the last decades the restless evolution of information and communication technologies (ICT) brought to a deep transformation of our habits. The growth of the Internet and the advances in hardware and software implementations modified our way to communicate and to share information. In this book, an overview of the major issues faced today by researchers in the field of radio communications is given through 35 high quality chapters written by specialists working in universities and research centers all over the world. Various aspects will be deeply discussed: channel modeling, beamforming, multiple antennas, cooperative networks, opportunistic scheduling, advanced admission control, handover management, systems performance assessment, routing issues in mobility conditions, localization, web security. Advanced techniques for the radio resource management will be discussed both in single and multiple radio technologies; either in infrastructure, mesh or ad hoc networks
