全局公平的自适应比例公平调度
Adaptive proportional fair scheduling with global-fairness
摘要
Abstract
Conventional proportional fair (PF) scheduling achieves fairness at the cost of the system 's rateperformance . Such fairness is characterized by long-term , and hence cannot guarantee the fairness ofsubscribers who enter the system temporarily or stay for just a short period of time . In addition , the delayrequirement of real-time service users can hardly be met . In order to remedy the above problems , wepropose an adaptive proportional fair ( APF) scheduling algorithm with global-fairness . The base stationdynamically adjusts the forgetting factor in the PF algorithm based on the degree of dispersion of all theusers' scheduling priorities so as to influence the update of users' scheduling weights . Simulation resultsshow that compared to conventional PF scheduling , the APF can achieve both the long-term and short-termfairness and high system sum-rate , and additionally guarantee good delay performance for users' service .关键词
