A Two-Threshold Optimal Sleeping Policy for a Single Server Queue with Bursty Traffic

摘要：

　　Making idle servers sleep is considered to be a key approach to reduce energy consumption of various information and communication systems.Optimal sleeping policies for a single server has been derived only for non-bursty traffic in prior work.In this talk,for the first time,we study the optimal sleeping policy for a single server queue with bursty traffic.Key factors including switch-over energy consumption as well as delay performance are considered.We formulate the problem as a POMDP(partially observable Markov decision process),and show that it can be solved by observing the time elapsed since the last arrival(TESLA).The optimal sleeping policy is shown to be a two-threshold policy and the simulation results show the effectiveness of the policy.Numerical results also show that traffic burstiness can help to enhance the system performance in terms of weighted sum of the energy-efficiency and delay.
