Approximation Algorithms for Mobile Data Caching in Small Cell Networks
(2014)Small cells constitute a promising solution for managing the mobile data growth that has overwhelmed network operators. Local caching of popular content items at the small cell base stations (SBSs) has been proposed to ... -
Approximation caching and routing algorithms for massive mobile data delivery
(2013)Small cells constitute a promising solution for managing the mobile data growth that has overwhelmed network operators. Local caching of popular content items at the small cell base stations has been proposed in order to ... -
Auction mechanisms for network resource allocation
(2010)In the autonomic Internet of the future, auction mechanisms arise as key methods for realizing efficient resource allocation. The major asset of auctions is their obliviousness to node utilities, which renders them capable ... -
Auction-based scheduling of wireless testbed resources
(2014)Experimentation in testbeds is gaining increasing ground as a necessary validation step for every theoretical study in communication networks. However, the first-come-first-served policy employed today by most testbeds ... -
Auction-Driven market mechanisms for dynamic spectrum management
(2011)There is nowadays unanimous agreement that spectrum should be allocated in a dynamic fashion so as to match the stochastic supply and demand by responding to spatiotemporal variations of spectrum availability and request. ... -
Bargaining-based mobile data offloading
(2014)The unprecedented growth of mobile data traffic challenges the performance and economic viability of today's cellular networks and calls for novel network architectures and communication solutions. Data offloading through ... -
C2M: Mobile data offloading to mesh networks
(2014)As the unprecedented growth of mobile data traffic places significant strain on cellular networks, alternative plans for exploiting already existing and under-utilized wireless infrastructure, become quite attractive. In ... -
Challenges in Auction Theory Driven Spectrum Management
(2011)Dynamic spectrum markets of the future will involve complex spectrum transactions among operators and users. The nontrivial dynamics in channel quality and spatiotemporal spectrum availability call for new ways of spectrum ... -
Collaborative placement and sharing of storage resources in the Smart Grid
(2015)The development of low-cost renewable energy generators transforms households into electricity prosumers. Given that generation from renewable sources is highly volatile and does not perfectly match the daily demand pattern ... -
Collusion of operators in wireless spectrum markets
(2012)The liberalization of wireless spectrum markets has been envisioned as a method for improving mobile communication services and accommodating the increasing traffic volumes of wireless users. It has been assumed that ... -
Competition and regulation in a wireless operator market: An evolutionary game perspective
(2012)We consider a communication market where a set of wireless operators compete over a large common pool of users. The latter have a reservation utility of U0 units or, equivalently, an alternative option to satisfy their ... -
Distributed resource allocation algorithms for peer-to-peer networks
(2008)In peer-to-peer networks, each peer plays the role of client and server. As server, it receives content requests made by other peers and needs to decide on what basis and to what extent it will satisfy these requests by ... -
Double Auction Mechanisms for Resource Allocation in Autonomous Networks
(2010)Auction mechanisms are used for allocating a resource among multiple agents with the objective to maximize social welfare. What makes auctions attractive is that they are agnostic to utility functions of agents. Auctions ... -
Economics of mobile data offloading
(2013)Mobile data offloading is a promising approach to alleviate network congestion and enhance quality of service (QoS) in mobile cellular networks. In this paper, we investigate the economics of mobile data offloading through ... -
Enabling crowd-sourced mobile Internet access
(2014)Crowd-sourced mobile Internet access services enable mobile users to connect with each other and share their Internet connections. This is a promising solution for addressing users' increasing needs for ubiquitous connectivity ... -
A framework for distributed bandwidth allocation in peer-to-peer networks
(2010)In peer-to-peer networks, each peer plays the role of client and server. As a server, it receives content requests of others and decides to what extent it will satisfy them by allocating upload bandwidth. As a client, it ... -
A framework for mobile data offloading to leased cache-endowed small cell networks
(2015)Cache-endowed small cell networks constitute a timely and effective solution for mobile network operators (MNOs) who strive to serve the massive content demand of the mobile users. However, the deployment of small cell ... -
Heterogeneous and opportunistic wireless networks
(2012)Recent years have witnessed the evolution of a large plethora of wireless technologies with different characteristics, as a response of the operators' and users' needs in terms of an efficient and ubiquitous delivery of ... -
Hybrid data pricing for network-assisted user-provided connectivity
(2014)User-provided connectivity (UPC) is a promising paradigm to achieve a low-cost ubiquitous connectivity. In this paper, we study a network-assisted UPC service model, where a mobile virtual network operator (MVNO) enables ...
