Experimental Results
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
