An Access Selection Prototype Based on IEEE 802.21
The Mobilia project is facing the new challenges appearing in the forthcoming wireless communication scenarios in which one of the distinctive factors is their intrinsic and remarkable heterogeneity. The evolution of the technologies has brought about the possibility of having terminals equipped with different interfaces, and thus the end-user device should be able to select the most suitable from a broad range of access alternatives. This paper presents an illustrative use case, based on a businessperson who presents different communication needs while traveling through heterogeneous networking scenarios. Starting from this point, we derive a set of requirements which should be addressed by Mobilia, following the concept of always best connected. Finally, the paper presents a platform developed so as to evaluate the entities performing the mobility management, handover decision algorithms and architectural protocol extensions, as proposed in the project.
