Storing and replication in topic-based publish/subscribe networks
(2010)
In current publish/subscribe networks messages are not stored and only active subscribers receive published messages. However, in a dynamic scenario a user may be interested in content published before the subscription ...
Service differentiation in multitier data centers
(2013)
In this paper, we study the problem of resource allocation in the setting of multitier data centers. Our main motivation and objective is to provide applications hosted in the data center with different service levels. In ...
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 ...
Dynamic CPU scheduling for QoS provisioning
(2013)
Distributed, large-scale, enterprise applications are commonly supported in multi-tier data-center environments. In this paper, we study a scheduling problem for sharing CPU time in a cluster of servers among a number of ...
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 ...
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 ...
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 ...
On the Wireless Network Coding with overhearing and index coding
(2013)
We study the problem of Wireless Network Coding with imperfect overhearing, a joint coding/scheduling problem that arises naturally in multihop wireless networks. We map this problem to specific instances of index coding. ...
Dynamic overload balancing in server farms
(2014)
We consider the problem of optimal load balancing in a server farm under overload conditions. A convex penalty minimization problem is studied to optimize queue overflow rates at the servers. We introduce a new class of ...
