Abstract

Modern digital cellular telephones and portable personal computers have created a new, practical, and challenging platform for distributed information processing. We have designed and implemented a communication architecture for the efficient integration of wired and wireless networks. The architecture is based on the principle of indirect interaction. The mediating interceptor, the Mobile-Connection Host, is the bridge between the wired and wireless networks. The architecture significantly improves the end-to-end performance of TCP/IP-based communication between mobile nodes and fixed hosts. The introduction of application-specific mediators in the mobile node and in the Mobile-Connection Host provides means for enhanced application-level functionality, better user-level control of the wireless link, and increased performance.
