      In this paper, a novel framework for enabling dynamic Policy and Charging Rules in modern 5G multi-tenancy environments is designed and presented. More specifically, adaptive pricing schemes are utilized by MNOs for ...

    • Energy efficient resource allocation scheme via auction-based offloading in next-generation heterogeneous networks 

      Bousia A. (2017)
      The focus of this chapter is centered on the network underutilization during low traffic periods (e.g., night zone), which enables the Mobile Network Operators (MNOs) to save energy by having their traffic served by ...

    • Energy-aware base stations: The effect of planning, management, and femto Layers 

      Koutitas, G.; Chiaraviglio, L.; Ciullo, D.; Meo, M.; Tassiulas, L. (2014)
      We compare the performance of three base station management schemes on three different network topologies. In addition, we explore the effect of offloading traffic to heterogeneous femtocell layer upon energy savings taking ...

    • Greening the Airwaves with Collaborating Mobile Network Operators 

      Koutitas G., Iosifidis G., Lannoo B., Tahon M., Verbrugge S., Ziridis P., Budzisz L., Meo M., Marsan M.A., Tassiulas L. (2016)
      Base station sharing is currently considered one of the most promising solutions for reducing the energy consumption costs of cellular networks. This paper presents a game theoretic framework for the study of such cooperative ...

    • An iterative double auction for mobile data offloading 

      Iosifidis, G.; Gao, L.; Huang, J.; Tassiulas, L. (2013)
      Mobile data offloading through complementary network technologies such as WiFi and femtocell can significantly alleviate network congestion and enhance users' QoS. In this paper we consider a market where mobile network ...

    • A Mechanism for Mobile Data Offloading to Wireless Mesh Networks 

      Apostolaras A., Iosifidis G., Chounos K., Korakis T., Tassiulas L. (2016)
      As the growth of mobile data traffic places significant strain on cellular networks, plans for exploiting under-utilized network resources become increasingly attractive. In this paper, we propose, design, and evaluate a ...
