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

In this paper we present experiences from adding soft ware mobility to mobile hand held computers In par ticular 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 plat form for several mobile code applications Through experience with these applications we have derived a 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
