A QoS autonomous decentralized protocol - QoS-ADP for real-time control system

In this paper, communication QoS property in autonomous decentralized real-time control system is defined. Conventional ADP realized the properties, such as reliability of data transmission, on-demand data distribution and on-line property. In order to achieve the time-deterministic property and assurance property, a QoS-ADP is proposed. The data filtering and arbitration mechanisms of QoS-ADP are also discussed. Finally, a prototype of QoS-ADP is implemented on Windows platform and LAN. The result of test and evaluation shows that the main features of QoS-ADP, such as time-deterministic data transmission, data flow control and assurance can be achieved.
