nImplemented MP3 player, encapsulated decoder as mobile agent, to execute locally or remotely
nVarious performance experiments, study impact of
Available Bandwidth (19.2 kbps 2 Mbps)
Relative CPU speed (Mobile CPU: Proxy
CPU)
n1:4 for laptop
as client device
n1:116 for
Windows CE palmtop as client device
nResults:
for high bandwidth and slow client,
offloading decoding agent to proxy can speed up application performance by
a factor of 20 and reduce power consumption by 95%
For faster
client devices, independent of bandwidth, no benefit (actually worse performance) when decoding sound samples
in access network
