Study on the Delay Performance of Station Dependent Two-level Polling Systems
摘要
Abstract
Based on priority differentiation and the system efficiency, this paper proposes a station dependent two-level polling system. The mixed service two-level polling system is extended by using queue state-dependent routing, in which only active stations with information packets could be visited by server. The scheme meets the requirement not only for conflict free but also for priority differentiation and efficiency, and provides a lower latency. An embedded Markov chain framework is set up to drive the closed-form expression for the mean waiting time. Numerical examples demonstrate that theoretical and simulation results are identical and the new system has a better efficiency at both key station and normal station.关键词
