A quality of service parameter associated with message traffic transmitted from a smart items infrastructure (102, 104, 106, 182) through a middleware message routing engine (150) to one or more enterprise applications (120-140, 183) is monitored (602). In response to the monitored quality of service parameter, a number of parallel message processors (174, 176, 178, 180) that route messages from the plurality of smart items to the message routing engine (150) is controlled (604).
