<p>The invention generally represents a true cross-layer integration of functions on several protocol layers within the network, thus providing a unified approach to QoS provisioning in a multihop network. In the unified approach according to the invention, connections are preferably determined by integrated optimization of a given objective function with respect to connection parameters on at least three protocol layers within the network. Perferably, the optimization involves routing (path selection), channel access as well as adaptation of physical link parameters. By incorporating physical connection parameters together with properly designed constraints, the issue of interference can be carefully considered. This means that it is possible to determine connection parameters that ensure substantially non-interfering communication with respect to existing connections as well as the new connection.</p> |
