Sustainability of service provisioning systems under attack
(2013)
We propose a resource allocation model that captures the interaction between legitimate users of a distributed service provisioning system with malicious intruders attempting to disrupt its operation. The system consists ...
Wireless network coding with partial overhearing information
(2013)
We study an 1-hop broadcast channel with two receivers. Due to overhearing channels, the receivers have side information which can be leveraged by interflow network coding techniques to provide throughput increase. In this ...
A modular framework for implementing joint wireless network coding and scheduling algorithms
(2013)
Intersession network coding (NC) can provide significant performance benefits via mixing packets at wireless routers; these benefits are especially pronounced when NC is applied in conjunction with intelligent scheduling. ...
Asymptotic Laws for Joint Content Replication and Delivery in Wireless Networks
(2013)
We investigate the scalability of multihop wireless communications, a major concern in networking, for the case that users access content replicated across the nodes. In contrast to the standard paradigm of randomly selected ...
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 ...
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 ...
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. ...
