Mowser - A Web Browser for Mobile Platforms
The World Wide Web was designed for static hosts, connected to static networks,
which are capable of sending and receiving large amounts of data without
significant delays. Mowser is a smart web browser designed to browse the WWW
from a mobile host, taking into account the user's preferences and network
In addition to network bandwidth limitations, mobile hosts also have relatively
less resources than their static counterparts. These include smaller screen
resolution and color capability, and limited or no sound capability. A smart Web
browser that is aware of these limitations will be able to better use its limited
bandwidth while browsing the World Wide Web.
Some features of Mowser which make
it better suited for browsing from a mobile host:
All the features of Mowser can be predetermined, or changed by the user,
depending on the network connection available.
- Smart Image downloading
- Awareness of the mobile host's color capabilities and screen resolution
allows Mowser to download only small images, that can be viewed easily. It will also automatically crop, scale and dither arbitrary images to a form appropriate for the users platform. The transformed image is associated with a link which will allow the user to get the actual image if s/he so desires.
- Smart Sound File downloading
- Once the mobile host's sound capabilities are known, Mowser will only
download sound files that can be played on the mobile host.
- File size Limiting
- Depending on the network connectivity available, the user can specify file
size limits for the different types of files that may be downloaded. Mowser can
then avoid lengthy file transfers to the mobile host. Assuming that the underlying network is capable of providing a Quality of Service measure of
the available bandwidth, this specification can also be given in terms of the maximum amount of time that should be allocated for a download.
Initial work on Mowser was done as a research project by
Greg Bernhardt, Sean McDermott, and Bun Tan, under the supervision of
Prof. Anupam Joshi.
Mowser is currently undergoing a complete rewrite to improve portability
and stability. Experimental results, source code, as well as a link to Mowser
will be available here by mid-July 1996.
This page will continue to be updated with information about Mowser and its
components.For further information, contact
