Challenges in Mobile Computing
–portability (of computing device):
nlimited power supply (battery)
ndata security (someone steals your laptop)
nsmall user interface (look at screen size of a PDA)
nlimited storage capacity (disks, for example,
are a “power liability”)
–solutions (or suggestions) exist to address all
these issues, however, the solutions are often conflicting:
ndo
not keep data on portable device to reduce security problem
ndo
not send data if not necessary to save valuable energy
