Introduction

• Ubiquitous Multimedia Communication
• Seamlessly meet and communicate anytime,
  anywhere, and from any device using any network
• Problems
• Host mobility
• How to preserve connectivity while changing IP
  address?
• How to automatically trigger a handover?
• What kind of data should be used for making the
  decision?
• How should the solution be designed in order to
  be deployable?
• Network heterogeneity
• How to manage bandwidth variations while also
  considering variations in demand for bandwidth?
• Session mobility
• How to preserve connectivity while changing
  device?
• How to automatically trigger a handover?
• What kind of data should be used for making the
  decision?

Discussion points

• The journal paper dilemma?
• Paper A contains the original idea, but paper B
  needs to contain parts of A to be readable.
  Should AB be in the thesis even if they overlap
  or should only B be there?
• How is deep and breadth defined, and who defines
  it? Is breadth defined as the number of papers,
  and deep the number of journal papers?
• Does the thesis really have to be error free?
  Also, what is defined as an error?
• Why is it more important be main author after
  lic.?
• Should the title reflect the vision or the
  content?
