motivation
Motivation

the characteristics and limitations of this environment affect a number of aspects of distributed computing and give birth to a number of interesting research challenges

Wireless mobile computing breaks the stationary

barrier and allows users to compute and access

information anywhere, anytime and from any device

However

final word
Final word

“The problem in times of turbulence is not the turbulence; it is acting with yesterday’s logic.”

Peter Drucker

If you’re trying to look far ahead, and what you see seems like science fiction, it might be wrong.

But if it doesn’t seem like science fiction, it’s definitely wrong.

Christine Peterson,

Foresight Institute
