An Architecture to Simplify Communicating Applications

This paper presents an overview of an architecture to facilitate the creation of communicating applications for handheld computers. We briefly introduce the overall goals of the project, the application model, and then describe the key features that support communicating application programs. Finally we walk through the execution of a communicating application to observe the application model in use. This paper only discusses hardware and operating system issues as they relate to applications. Communications issues, such as modem dialing or wireless considerations are not covered, as they are hidden from most application programs. Introduction We believe a mobile computer must communicate to be useful; thus we have designed communications into our handheld computer system from the very beginning. This paper describes a research project that has undertaken the design of operating system and application software for a prototype handheld computer. We view the handheld computer as a mobi..
