Mobile Computing

• (^) A simple definition could be: Mobile Computing is using a computer (of one kind or another) while on the move
• (^) Another definition could be: Mobile Computing is when a work process is moved from a normal fixed position to a more dynamic position
• (^) A third definition could be: Mobile Computing is when a work process is carried out somewhere where it was not previously possible
• (^) Mobile Computing is an umbrella term used to describe technologies that enable people to access services anytime and anywhere

Mobile Computing

• (^) Many other names/overlapping computing paradigms:
  • (^) Pervasive Computing
  • (^) Ubiquitous Computing
  • (^) Wireless Systems
  • (^) Internet of Things (IoT)
  • (^) Embedded Computing
  • (^) Nomadic Computing
  • (^) Wireless Sensor Networks
  • (^) (Mobile) Ad-Hoc Networks
  • (^) Mesh Networks
  • (^) Vehicular Networks
  • (^) …

Wired vs Wireless

• (^) Wired Networks
  • (^) high bandwidth
  • (^) low bandwidth variability
  • (^) can listen on wire
  • (^) high power machines
  • (^) high resource machines
  • (^) need physical access (security)
  • (^) low delay
  • (^) connected operation
    • (^) Mobile Networks
      • (^) low bandwidth
      • (^) high bandwidth variability
      • (^) hidden terminal problem
      • (^) low power machines
      • (^) low resource machines
      • (^) need proximity
      • (^) higher delay
      • (^) disconnected operation

Why Go Mobile?

• (^) Enable anywhere/anytime connectivity
• (^) Bring computer communications to areas without pre- existing infrastructure
• (^) Enable mobility
• (^) Enable new applications
• (^) An exciting new research area

Portability

• (^) Reducing the size of hardware to enable the creation of computers that could be physically moved around relatively easily

Miniaturization

• (^) Creating new and significantly smaller mobile form factors that allowed the use of personal mobile devices while on the move

Convergence

• (^) Integrating emerging types of digital mobile devices, such as Personal Digital Assistants (PDAs), mobile phones, music players, cameras, games, etc., into hybrid devices

Divergence

• (^) Opposite approach to interaction design by promoting information appliances with specialized functionality rather than generalized ones

Digital Ecosystems

• (^) The emerging wave of digital ecosystems is about the larger wholes of pervasive and interrelated technologies that interactive mobile systems are increasingly becoming a part of

Example: Smartphone

• (^) Portability: carry it anywhere you want
• (^) Miniaturization: make it possible to build device to fit in your pocket
• (^) Connectivity: Wi-Fi, LTE/4G, cellular, Bluetooth
• (^) Convergence: phone, camera, gaming device, movie streaming, music player, …
• (^) Divergence:?
• (^) Applications: “Rise of the Apps”
• (^) Digital Ecosystem: social networks, distributed gaming, video streaming, work apps, …
