A plan for our examination of wireless application and API design was presented at IWQoS'96, and led to the design of an API now called "CoMMA". A more current overview of current directions in the Shoshin's mobile project, including hardware details, is also availble.

Plans are also under way with Bell Mobility to examine client-server applications for portable devices operating in wireless environments ( details).
