Abstract

A true cross-layer integration of functions is provided on several protocol layers within a network, thus providing a unified approach to Quality of Service (QoS) provisioning in a multihop network. In the unified approach, 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. Preferably, 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. It is thereby possible to determine connection parameters that ensure substantially non-interfering communication with respect to existing connections as well as the new connection.
