- | As said in the presentation of this website, we are working on the field of pervasive computing. In such a setting, context will play an important role. The context consists of all the information and services | + | We claim that in order to deal with context-dependent communications in mobile networks, we need a model that satisfies |

- | Ambient references unify two concepts: they are both a peer-to-peer discovery channel | + | The problem with the split objects model is that the message sender must know before hand which are the roles a receiver could take. In dynamic environments like mobile open networks, this acknowledgment is practically impossible and undesirable (due to the heterogeneity and autonomicity of the participants). Hence we have extended this model in such a way that the sender only have to include its own context information in the messages (and not a role). At the receiver side there will be a reasoning engine that will take as input the context of both sender and receiver, and will map this information to a role. We have called this entity the context-dependent role selector. For further information about this solution, we refer the interested reader |
