PROPOSAL OF POLLED-CSMA PROTOCOL FOR AN AD HOC SCADA SYSTEM(International Foundation for Telemetering, 2000-10)In this paper we introduce an ad hoc distributed supervisory control and data acquisition (SCADA) system, which covers two types of traffic, a small number of slave stations with stream traffic and much larger number of slave stations with burst traffic. To improve the system’s real-time transmission and channel allocation efficiency, a MAC scheme, named Polled-CSMA, is designed by integrating the merits of polling and CSMA protocols. Extensive analysis shows that this MAC protocol meets the system’s QOS requirements.
