Context-Aware Computing

5.4.6.3Distribution

Context-aware ambient intelligent spaces incorporate many components. Moreover, several contiguous spaces might coexist. Such a distribution nature introduces many challenging issues. One of them is related to event detection (for triggering context degradation in the LCP model). Although some local events (monitored within the internal AmI space) might be broadcast to any internal recipient responsible for managing context data associated with the LCP, it is difficult to assume that external events (monitored in another context-aware space) will be. In fact, events themselves constitute parts of context information, and as such may be regulated by LCPs leading to their own progressive degradation (which can occur rapidly). ...
