BIRD-VNE: Backtrack-avoidance virtual network embedding in polynomial time
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The virtual network embedding (VNE) problem is known to be NP-hard, and as a result, several heuristic approaches have been proposed to solve it. These heuristics find sub-optimal solutions in polynomial time, but have ...
Efficient datacenter resource utilization through cloud resource overcommitment
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
We propose an efficient resource allocation framework for overcommitted clouds that makes great energy savings by 1) minimizing PM overloads via resource usage prediction, and 2) reducing the number of active PMs via ...
Distributed fair spectrum assignment for large-scale wireless DSA networks
(
Springer Verlag
, 2015 , Conference Paper)
This paper proposes a distributed and fair resource allocation scheme for large-scale wireless dynamic spectrum access networks based on particle filtering theory. We introduce a proportionally fair global objective function ...
Power allocation analysis for dynamic power utility in cognitive radio systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The focus of this paper is to investigate the fundamental limits of power allocation when taking into account a dynamic power pricing scheme. This paper proposes an optimal power allocation analysis for wireless systems ...
Design and implementation of credit-based resource allocation protocol for DSA systems
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper designs, implements, and evaluates an efficient dynamic spectrum access (DSA) protocol for cognitive radio networks. The proposed protocol relies on the concept of credit value to allocate resources among users ...
Online assignment and placement of cloud task requests with heterogeneous requirements
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Managing cloud resources in a way that reduces the consumed energy while also meeting clients demands is a challenging task. In this paper, we propose an energy-aware resource allocation framework that: i) places the ...
Joint resource scheduling and peak power shaving for cloud data centers with distributed Uninterruptible power Supply
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
The grid company enforces high penalties for the peak power demands of cloud data centers. These high penalties result in high electricity bill that can be avoided by relying on the servers' Uninterruptible Power Supply ...
