The functionality provided by a wireless communication system can usually be partitioned into submodules, the so-called layers [21]. With each layer, a set of variable parameters can be associated. For example, common physical layer parameters are power allocation, allocation of time slots, beamforming vectors, choice of modulation and coding schemes, etc. Possible parameters at upper layers are scheduling decision, choice of a route, and, at the application layer, source coding rate. Parameters are variable in the sense that for each parameter there exists a set of possible values to choose from. Moreover, each parameters impacts overall system performance in a certain way. Generally speaking, then, a parameter optimization corresponds to optimizing system performance with respect to all variable parameters over the set of all possible parameter setups.
