Mobile software on mobile hardware. Experiences with TACOMA on PDAs.

Abstract

In this paper, we present experiences from adding software mobility to mobile, hand-held computers. In particular, we have built TACOMA Lite, a mobile code system, for this environment. With TACOMA Lite installed, hand-held computers can host and execute mobile code. TACOMA Lite has been used as platform for several mobile code applications. Through experience with these applications, we have derived a 3-layer software architecture suitable for this type of mobile computing. We conclude that, given certain constraints, mobile software can be a useful artifact in this environment.
