To solve the problem of the priorities of network traffic and improve the applicability of multi-access for communication systems, a two-level asymmetric polling control system was proposed, in which the central node adopts an exhaustive access policy and the normal nodes adopt an asymmetric 1-limited (K = 1) access policy. This model can distinguish network traffic priorities as well as guarantee fairness of the system. Using a probability generating function and embedded Markov chain, the system model was established. Through the accurate mathematical analysis of the system model, the mathematical analytical formulas of important system performance parameters, such as the mean queue length of nodes and the mean delay of information packets, were obtained. The model provides high-quality services for high-priority nodes while maintaining the quality of service at low-priority nodes. Finally, the polling access control strategy was implemented by Tinyos.

Key words: polling control system, priorities, asymmetric 1-limited (K = 1) service, fairness, TinyOS
