An evolutionary method of producing a medium access control unit, the unit determines whether to either transmit data or to back off for a period of time. The method comprises assembling, from a language set of terms, sequences of terms each capable of being parsed in accordance with a programming language. The set of terms could comprise functions relevant to MAC processes. The fitness of each of the parsed sequences of terms is determined according to a predetermined fitness function. If a process termination criterion has not been met then one or more of the sequences of terms is selected in response to their determined fitness, further sequences of terms are generated and the fitness values for this further set are then evaluated. When the termination criterion has been met, one of the sequences is selected in response to its determined fitness to provide the function to be used for the transmission decision. This MAC unit could be used as part of a device on a wireless communication network. Also disclosed is a method in which the process employed to make the transmission decision is evolved in response to a set of environmental conditions. |
