The impact of storage capacity on end-to-end delay in time varying networks
Iosifidis, G.; Koutsopoulos, I.; Smaragdakis, G. (2011)Recent technological advances have rendered storage a cheap and at large scale available resource. Yet, there exist only few examples in networking that consider storage for enhancing data transfer capabilities. In this ... -
Incentive mechanisms for hierarchical spectrum markets
Iosifidis, G.; Chorppath, A. K.; Alpcan, T.; Koutsopoulos, I. (2012)We study spectrum allocation mechanisms in hierarchical multi-layer markets which are expected to proliferate in the near future according to the evolving spectrum policy reform proposals. We consider the scenario that ... -
Incentive mechanisms for user-provided networks
Iosifidis, G.; Gao, L.; Huang, J.; Tassiulas, L. (2014)The increasing mobile data demand and the proliferation of advanced handheld devices place user-provided networks in a conspicuous position for next-generation network architectures. There has been growing consensus that ... -
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 ... -
Multicast-aware caching for small cell networks
Poularakis, K.; Iosifidis, G.; Sourlas, V.; Tassiulas, L. (2014)The deployment of small cells is expected to gain huge momentum in the near future, as a solution for managing the skyrocketing mobile data demand growth. Local caching of popular files at the small cell base stations has ... -
Reputation-assisted utility maximization algorithms for peer-to-peer networks
Iosifidis, G.; Koutsopoulos, I. (2008)Peer-to-peer networks are voluntary resource sharing systems among rational agents that are resource providers and consumers. While altruistic resource sharing is necessary for efficient operation, this can only be imposed ... -
The ultimate limits of wireless networks
Antón-Haro, C.; Eldar, Y.; Galluccio, L.; Iosifidis, G.; Kountouris, M.; Koutsopoulos, I.; Matamoros, J.; Palazzo, S.; Shamai, S.; Belleville, M.; Ramakrishnan, V.; Masera, G.; Morche, D. (2012)This paper discusses the grand challenges associated with the holy grail of understanding and reaching the ultimate performance limits of wireless networks. Specifically, the next goal in the networking community is to ... -
Video delivery over heterogeneous cellular networks: Optimizing cost and performance
Poularakis, K.; Iosifidis, G.; Argyriou, A.; Tassiulas, L. (2014)Video delivery to mobile users is one of the largest challenges that network operators face today. In this work we consider a heterogeneous cellular network with storage capable small-cell base stations, and study this ...
