Abstract

Mobility is being touted as a next step in the computing revolution. Increased mobility implies increased reliance on wireless networks. However, techniques and tools for handling the variable and generally lower Quality of Service (QoS) offered by this type of network have not yet emerged. This problem is exacerbated by the fact that the standard communication protocols are unable to exploit such QoS as is available. Finally, advances in PCMCIA card technology mean that mobile applications must deal with a changeable computing platform. The combined inability of applications to adapt to a varying execution environment and the poor performance of communication protocols in a mobile environment have led us to develop a mobile application support architecture called the Communication Manager for Mobile Applications (Comma). Comma enables adaptive applications by providing methods for execution environment monitoring, protocol manipulation, and communication stream manipulation.
