• Energy aware buffer aided cooperative relay selection 

      Hadef, M.; Apostolaras, A.; O'Reillys, J.; Mourad, A.; Mouhouche, B.; Koutsopoulos, I.; Korakis, T.; Tassiulas, L. (2014)
      In this paper we evaluate an energy-aware relay selection mechanism which exploits channel state information and the availability of buffers at relays to perform flexible relaying based on a backpressure-driven optimization ...
    • Layered backpressure scheduling for delay reduction in ad hoc networks 

      Maglaras, L. A.; Katsaros, D. (2011)
      Packet scheduling in wireless ad hoc networks is a fundamental problem for ad hoc networking. Backpressure scheduling is a solid and throughput optimal policy for such networks, but suffers from increased delays. In this ...
    • Minimal Evacuation Times and Stability 

      Georgiadis, L.; Paschos, G. S.; Libman, L.; Tassiulas, L. (2015)
      We consider a system where packets (jobs) arrive for processing using one of the policies in a given class. We study the connection between the minimal evacuation time and the stability region of the system and show that ...
