–there
seems to be general agreement that some sort of application
partitioning is a good thing:
n reduce bandwidth
requirements
novercome the physical limitations of the mobile
computer
–one
open question: how do you partition and when?
nstatic partitioning is easier (and we will see examples
for WWW later)
nhowever, computation environment can change radically during
execution:
–MH
moves to area with better networking infrastructure (maybe gets
back into his docking station)
–PCMCIA
cards all of a sudden add more memory
–radio
signal is dropped completely temporarily
nimplies growing interest in dynamic application
partitioning
