Social Network Analysis Concepts in the Design of Wireless Ad Hoc Network Protocols
(2010)
This article presents a survey of ad hoc networking protocols that have used concepts such as centrality metrics and community formation from the area of social network analysis, which is seen as a network measurement task ...
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 ...
Minimal Evacuation Times and Stability
(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 ...
Deployment Strategies and Energy Efficiency of Cellular Networks
(2012)
The energy efficiency of cellular networks is explored for different network deployment strategies and traffic conditions. The total network power consumption and the ratios Watts/kbps, Watts/user are used as metrics to ...
Smart Grid Technologies for Future Radio and Data Center Networks
(2014)
This article explores smart grid technologies that can be applied to a telecommunication network to achieve energy-efficient networking, autonomous operation, and adaptation to real-time electricity pricing schemes. With ...
Enhancing wireless networks with caching: Asymptotic laws, sustainability & trade-offs
(2014)
We investigate on the sustainability of multihop wireless communications in the context of Information-Centric Networks, when content is replicated in caches over the network. The problem is cast in a flat wireless network ...
Storage planning and replica assignment in content-centric publish/subscribe networks
(2011)
Content-centric publish/subscribe networking is a flexible communication model that meets the requirements of the content distribution in the Internet, where information needs to be addressed by semantic attributes rather ...
Dynamic Wireless Network Coding With Overhearing and Variable Channel Rates
(2015)
We study a one-hop broadcast channel with two receivers. The receivers have side information obtained by overhearing wireless channels. The relay takes control decisions by coding transmissions based on its knowledge of ...
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 ...
Optimal Transmission Rate Control Policies in a Wireless Link Under Partial State Information
(2010)
We consider the problem of PHY layer transmission rate control for maximum throughput on a wireless link over a finite time horizon. For each link state there exists a most advantageous transmission rate for the controller. ...
