Optimal overload response in sensor networks
(2006)
A single commodity network that models the information flow in an arbitrary topology sensor field that collects and forwards information to a backbone through certain designated gateway nodes is considered. Resilient ...
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). ...
Resource allocation and cross-layer control in wireless networks
(2006)
Information flow in a telecommunication network is accomplished through the interaction of mechanisms at various design layers with the end goal of supporting the information exchange needs of the applications. In wireless ...
A MAC protocol for full exploitation of directional antennas in ad-hoc wireless networks
(2003)
Directional antennas in ad hoc networks offer many benefits compared with classical omnidirectional antennas. The most important include significant increase of spatial reuse, coverage range and subsequently network capacity ...
Pricing strategies for differentiated services content delivery networks
(2005)
In order to reduce the user latency, the web sites disseminate some of their information to surrogate caches located closer to the users. We discuss a simple differentiated service type architecture for content delivery ...
An architecture for secure VoiIP and collaboration applications
(2007)
VoIP and collaboration Internet applications are a driving force for the use and expansion of the Internet. Current applications usually require end user registration in a central user database, which in turn provides ...
Policy distribution using the publish/subscribe paradigm for managing MANETs
(2008)
Policy management has been an emerging management paradigm that has been extensively studied for the case of fixed networks and limited work has already been done for migrating it to mobile environments. Publish/subscribe ...
Distribute, store and retrieve management policies in wireless ad-hoc networks using the content delivery publish/subscribe paradigm
(2009)
Policy management is a management paradigm that has been extensively studied for the case of fixed networks but limited work can be found for migrating it to mobile environments. It enables dynamic adaptation of the network ...
