Proposal of a Hierarchical and Distributed Method for Selecting a Radio Network and a Transmission Mode

The deployment of heterogeneous radio networks and the deployment of Unicast Internet Protocol IP/Multicast IP architectures can impact the quality of services received by the users. The authors think that they will accept these quality variations if they have the possibility to choose the radio network and the transmission mode, multicast versus unicast. But, when choosing a radio network or a transmission mode, the choices of the users can be opposed to the choices of the operators managing the networks. To overcome this drawback, the authors defined a method allowing the users, the operators managing the networks and the service providers to cooperate in the selection process.
