ABSTRACT
ABSTRACT This chapter addresses research on context-aware systems for mobility and multihoming, in the scope of ambient assisted living. Always-on connectivity requires efficient management of radio access technologies to enable a terminal device to communicate more effectively. We focus on context-aware systems for mobility management, which are applied to aid the handover process. Based on learning data, users’ connectivity can be optimized by deploying entities that have functional intelligence and consistent background knowledge at their disposal. This will enable clever decisions to be made,
