Abstract : Many techniques for the enhancement of the quality of control have been studied in the networked control systems based on differentiated services, synchronization or dynamic aproaches. By controlling the resources of the network, a compromise between the offered quality of service and the required quality of control can be established. In the case of a multi hop control loop, using IEEE 802.15.4 for instance, the quality of control can be affected by the inherent network factors (e.g. the load of traffic, the delay, the jitter). These factors must be considered when the quality of control techniques are applied. By using an on line adaptation of quality of control and some other techniques, we analyze the behavior of the control systems when the control loop includes multi hop paths. Simulation results show the effects of delay components derived from the multi hop paths of the control loop.
