DGPS for Mobile Users: A Mobile Agent Approach

As the computational power of mobile devices increases, so does the demand for more sophisticated applications and services. In particular the demand for location-aware services is likely to increase substantially. Such services will vary in how accurate a position solution they will require. However, there can be little doubt that some will require an accuracy that can only be provided through DGPS. In this paper we propose a solution based on mobile agents. In particular, we envisage agent migrating to applications, hosted on mobile devices, and delivering a DGPS solution. It is assumed that GPS is available locally on the device and that a wireless connection to SISNet server is available.
