    • A modeling framework for optimizing the flow-level scheduling with time-varying channels 

      Ayesta U.; Erausquin M.; Jacko P. (Performance Evaluation, 2010-12-31)
      We introduce a comprehensive modeling framework for the problem of scheduling a finite number of finite-length jobs where the available service rate is time-varying. The main motivation comes from wireless data networks ...
    • Nearly-optimal scheduling of users with Markovian time-varying transmission rates 

      Cecchi F.; Jacko P. (Performance Evaluation, 2016-01-01)
      We address the problem of developing a well-performing and implementable scheduler of users with wireless connections to the central controller, which arise in areas such as mobile data networks, heterogeneous networks, ...
    • Scheduling of users with Markovian time-varying transmission rates 

      Cecchi F.; Jacko P. (Performance Evaluation Review, 2013-12-31)
      We address the problem of developing a well-performing and implementable scheduler of users with wireless connection to the base station. The main feature of such real-life systems is that the quality conditions of the ...
    • Stability and asymptotic optimality of opportunistic schedulers in wireless systems 

      Ayesta U.; Erausquin M.; Jonckheere M.; Verloop I.M. (VALUETOOLS 2011 - 5th International ICST Conference on Performance Evaluation Methodologies and Tools, 2011-12-31)
      We investigate the scheduling of a common resource between several concurrent users when the feasible transmission rate of each user varies randomly over time. Time is slotted and users arrive and depart upon service ...
