Abstract
In this paper, we present a proxy based system
(MOWSER) to support web browsing from mobile clients
over wireless networks. Mowser is a proxy agent between
the mobile host and the web server, which performs active
transcoding of data on both upstream and downstream traf-
c to present web information to the mobile user according
to the QoS parameters set by the user. Active transcoding is
de ned as modifying the HTTP stream in situ, and it is en-
tirely transparent to the user. Further, our system does not
pose any additional requirements on the mobile user. This
is an improvement over other proxy based systems, which
only transcode images on the downstream and are mostly
not con gurable. While developed for mobile users, such a
system can actually be useful in any low bandwidth scenario.
