Abstract :
Simulation is an essential tool for performance evaluation of communication networks. We are interested in the waiting time W of packets. The control variates method profits from the knowledge of another stochastic process strongly correlated with W to reduce the uncertainty in the estimation of its mean. We analyze the usefulness of the cycle time as a control stochastic process for medium access control (MAC) protocols with polling service discipline, showing its potential and drawbacks. We propose a control variate that overcomes the disadvantages of cycle time and show its behavior in a case study. This new control variate will also be useful in the case of other MAC protocols
