A proposed architecture for context-aware mobility management

Mobility management is one area where context-awareness can be of great use. However, most context-management systems have been developed for smart spaces and are not designed for highly mobile devices. We propose an architecture for context-aware mobility management that is both distributed and hierarchical. The architecture consists of a global context server, a number of local proxy and adaptation servers, and the mobile nodes. Our architecture is unique in that both the local servers and the mobile nodes make mobility decisions, instead of having all the intelligence reside on network side components or central servers only, as is the case in most context management systems.
