Transcript

  • 1. Seminário - Computação MóvelLuis Felipe CiprianiProf.Alfredo Goldman - 06/06/2013 - IME USP[1]
  • 2. • Sistemas Pervasivos• Sistemas Pervasivos de Larga Escala• Origins Model• Por que precisamos de Modelos de Programação?• Toolkit
  • 3. Ubíquo vs Pervasivo[7]
  • 4. “The most profound technologies arethose that disappear. They weavethemselves into the fabric of everyday lifeuntil they are indistinguishable from it.”Mark Weiser (1991) [2]
  • 5. Primeira Onda[4]
  • 6. Segunda Onda[4]
  • 7. Terceira Onda[4]
  • 8. [3]
  • 9. [8]
  • 10. Jawbone up (https://jawbone.com/up)
  • 11. E em Larga Escala?
  • 12. • utiliza um grande número de fontes de dados• processa imensos montantes de dados em tempo real• provê serviços para várias aplicações que necessitamdo contexto oferecido• deve lidar com a grande volatilidade do ambiente
  • 13. [5]
  • 14. [6]
  • 15. Smart dust
  • 16. OriginsProgrammingModel[9]
  • 17. Sistema PervasivoContext-Aware Application (CA)Context Source (CS)
  • 18. [1]
  • 19. Por que precisamos de ummodelo de programação[10]
  • 20. • facilitar o desenvolvimento de aplicações cientesde contexto• oferecer um design que possibilita a fácilescalabilidade• encapsular o consumo de das fontes de dadosObjetivos de uma origin...mas como ele faz isso?
  • 21. Estrutura e Características de uma origin[1]
  • 22. Operações de processamento de uma originmonitor [1]
  • 23. Origins Toolkit[11]
  • 24. http://akka.io/
  • 25. [1]
  • 26. [1]
  • 27. [1]
  • 28. [1]
  • 29. [1]
  • 30. [1]
  • 31. Conclusão
  • 32. • Modelo se apóia em bons princípios paraimplementação de sistemas em larga escala• Suporta operações básicas que quando associadaspodem criar operações mais complexas• Possui características que também permitem o seu usoem sistemas pervasivos de larga escala• Porém, faltou exemplos de usos reais e acesso aimplementação do toolkit para uma melhor avaliação• Trabalhos relacionados a esse focam em sistemaspervasivos de pequena escala.
