A Dynamic Updating Mechanism of Devices in Pervasive Computing Environments

Devices are the key of the pervasive computing applications to acquire the context changing and also take the responding actions.Since device updating happens occasionally in a running pervasive application,it is necessary to study how to minimize the cost of renewal to popularize the application.Based on our former work,which is an adaptive and scalable context-aware architecture for pervasive computing and its prototype is implemented based on OSGi/R-OSGi,this paper proposes a dynamic updating mechanism of devices to solve the problem related with the device heterogeneity.With this mechanism the developers of the application need not to be involved in device updating.
