    • Mapping time-varying IP traffic to flexible optical paths in flexgrid optical networks 

      Tunc C.; Akar, N. (Springer New York LLC, 2015)
      A spectrum slot is the frequency range allocated to a single channel within a flexible grid, and its width needs to be an integer multiple of the so-called slot width granularity. The slot width of the spectrum slots to ...
    • MPLS automatic bandwidth allocation via adaptive hysteresis 

      Akar, N.; Toksöz, M. A. (Elsevier, 2010-11-29)
      MPLS automatic bandwidth allocation (or provisioning) refers to the process of dynamically updating the bandwidth allocation of a label switched path on the basis of actual aggregate traffic demand on this path. Since ...
    • Optimal streaming under rate constraints (İngilizce) 

      Gurses, E.; Akar G.B.; Akar, N. (2006)
      In this paper, we propose an optimal video streaming framework using retransmissions based on the theory of Markov Decision Processes (MDP). Using MDPs, we calculate average reward optimal policies so as to maximize the ...
    • Trajectory control of a quadrotor using a control allocation approach 

      Zaki, H.; Unel, M.; Yildiz, Y. (IEEE (Institute of Electrical and Electronics Engineers), 2017)
      A quadrotor is an underactuated unmanned aerial vehicle with four inputs to control the dynamics. Trajectory control of a quadrotor is a challenging task and usually tackled in a hierarchical framework where desired/reference ...
