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 ...
Distributed topology construction of Bluetooth wireless personal area networks
(2005)
Bluetooth, a wireless technology based on a frequency-hopping physical layer, enables portable devices to form short-range wireless ad hoc networks. Bluetooth hosts are not able to communicate unless they have previously ...
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 ...
Layered multicast rate control based on Lagrangian relaxation and dynamic programming
(2006)
In this paper, we address the rate control problem for layered multicast traffic, with the objective of solving a generalized throughput/fairness objective. Our approach is based on a combination of Lagrangian relaxation ...
Convex approximation techniques for joint multiuser downlink beamforming and admission control
(2008)
Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UNITS, 802.16e). ...
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 ...
