[en] FAULT TOLERANCE OF MOBILITY AGENTS OF PROTOCOL MOBILE IP / [pt] TOLERÂNCIA À FALHA DOS AGENTES DE MOBILIDADE DO PROTOCOLO MOBILE IPLUCIANO DA SILVA SANTOS 16 December 2005 (has links)
[pt] O crescimento da Internet, tanto do ponto de vista do
número de usuários
como dos serviços oferecidos, e o rápido progresso da
tecnologia de comunicação
sem fio, tornou possível uma demanda crescente por
sistemas sem fios que
permitam o acesso a Internet. Porém, um dos principais
fatores desafiadores para
o desenvolvimento desta nova forma de acesso é a
mobilidade das estações
móveis. A fim de resolver todos os problemas relacionados
à introdução da
mobilidade nesta nova forma de acesso, a Internet
Engineering Task Force (IETF)
através de pesquisas definiu o Mobile IP como o protocolo
padrão para esse novo
cenário. Embora este protocolo receba inúmeras
contribuições que visam
melhorar o seu desempenho tanto nas questões de handoff e
de segurança dos
registros dos usuários, este protocolo não recebe a mesma
atenção para a questão
da falha dos seus Agentes de Mobilidade. Estes agentes
suportam as conexões das
estações móveis integrando as redes sem fio com as redes
IP amplamente
difundida. Portanto, o objetivo desta dissertação é
apresentar uma proposta de
tolerância à falha dos Agentes de Mobilidade a fim de
contribuir nesta linha de
pesquisa. / [en] The growth of the Internet, as much of the point of view
of the number of

the wireless
communication technology, it became possible a demand for
wireless systems that
allow the access the Internet. However, one of the main
challenging factors for the
development this new access way is the mobility of the
mobile stations. In order
to solve all of the problems related to the introduction
of the mobility in this new
access form, the Internet Engineering Task Forces (IETF)
through researches it
defined Mobile IP as the standard protocol for that new
scenery. Although this
protocol receives countless contributions that seek to
improve it so much acting in
the handoff subjects and of safety of the users'
registrations, this protocol doesn't
receive the same attention for the subject of the fault of
their Mobility Agents.
These agents support the connections of the mobile
stations integrating the
wireless networks with IP netowrks spread. Therefore, the
objective of this
dissertation is to present a proposal of fault tolerance
of the Mobility Agents in
order to contribute in this research line.

Mobile IP v sítích MANET / Mobile IP in MANETsRaška, Martin January 2009 (has links)
This thesis discuss about the problem with mobility of stations in IP networks, concretely protocol Mobile IP and about the problems with this protocol in MANET networks, with the scope on Motorola MESH. First part is about design integration of protocol Mobile IP in this networks with usage Tropos 5210 MetroMesh routers and Cisco components (router, switch) to design and configure wireless MESH network, than connect this network with Cisco components and try to implement Mobile IP into this network. Second part is about design and configure wireless network from Cisco Wireless Access Points and about succesfully implementation of Mobile IP protocol into this network. In the last part is some tests of the function and quality of this topology.
