Autonomic cache management in Information-Centric Networks
(2012)Recent research efforts in the area of future networks indicate Information-Centric Networking (ICN) as the dominant architecture for the Future Internet. The main promise of ICN is that of shifting the communication ... -
Client and server games in peer-to-peer networks
(2009)We consider a content sharing network of noncooperative peers. The strategy set of each peer comprises, (i) client strategies, namely feasible request load splits to servers, and (ii) server strategies, namely scheduling ... -
Client-server games and their equilibria in peer-to-peer networks
(2014)In peer-to-peer networks, each peer acts simultaneously as client and server, by issuing and satisfying content requests respectively. In this work, we use concepts from non-cooperative game theory to model the interaction ... -
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 ... -
Distributed cache management in information-centric networks
(2013)The main promise of current research efforts in the area of Information-Centric Networking (ICN) architectures is to optimize the dissemination of information within transient communication relationships of endpoints. ... -
An efficient probing mechanism for next generation mobile broadband systems
(2012)Opportunistic scheduling exploits multiuser diversity for improving the performance of wireless systems. However, it requires instantaneous channel state information (CSI) to be available at the transmitter side. Since ... -
Electricity markets meet the home through demand response
(2012)Demand response (DR) programs motivate home users through dynamic pricing to shift electricity consumption from peak demand periods. In this paper, we introduce a day ahead electricity market where the operator sets the ... -
Geometrical bounds on the efficiency of wireless network coding
(2013)This paper explores wireless network coding both in case of deterministic and random point patterns. Using the Boolean connectivity model we provide upper bounds for the maximum encoding number, i.e., the number of packets ... -
Low complexity algorithms for relay selection and power control in interference-limited environments
(2010)We consider an interference-limited wireless network, where multiple source-destination pairs compete for the same pool of relay nodes. In an attempt to maximize the sum rate of the system, we address the joint problem of ... -
Medium access games: The impact of energy constraints
(2011)We consider random medium access schemes for devices that support sleep modes, i.e. turning off electronic compartments for energy saving. Due to hardware limitations, sleep mode transitions cannot occur at the medium ... -
On-line storage management with distributed decision making for content-centric networks
(2011)Content traffic proliferation in Internet makes more dire than ever the development of radical new network architectures, where information will be addressed by semantic attributes rather than the origin and destination ... -
The Role of Aggregators in Smart Grid Demand Response Markets
(2013)The design of efficient Demand Response (DR) mechanisms for the residential sector entails significant challenges, due to the large number of home users and the negligible impact of each of them on the market. In this ...
