Maximum throughput of a cooperative energy harvesting cognitive radio user
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate the maximum throughput of a saturated rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU harvests energy packets (tokens) from the environment with a certain ...
Multi-user diversity with optimal power allocation in spectrum sharing under average interference power constraint
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate the performance of multi-user diversity (MUD) with optimal power allocation (OPA) in spectrum sharing (SS) under average interference power (AIP) constraint. In particular, OPA through average ...
Maximum throughput of a secondary user cooperating with an energy-aware primary user
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energy saving. Time is slotted and users are ...
Probabilistic band-splitting for a buffered cooperative cognitive terminal
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we propose a cognitive protocol that involves cooperation between the primary and secondary users. In addition to its own queue, the secondary user (SU) has a queue to store, and then relay, the undelivered ...
Online multi-resource scheduling for minimum task completion time in cloud servers
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
We design a simple and efficient online scheme for scheduling cloud tasks requesting multiple resources, such as CPU and memory. The proposed scheme reduces the queuing delay of the cloud tasks by accounting for their ...
Design and implementation of distributed dynamic spectrum allocation protocol
(
IEEE Computer Society
, 2014 , Conference Paper)
In this paper, we design, implement, and evaluate a resource allocation protocol for distributed dynamic spectrum access (DSA). This protocol, based on learning techniques, enables users to locate and exploit unused spectrum ...
Distributed dynamic spectrum access with adaptive power allocation: Energy efficiency and cross-layer awareness
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper proposes energy and cross-layer aware resource allocation techniques that allow dynamic spectrum access users, by means of learning algorithms, to locate and exploit unused spectrum opportunities effectively. ...
An adaptive route optimization scheme for nested mobile IPv6 NEMO environment
(
IEEE Computer Society
, 2014 , Conference Paper)
We address the route optimization problem for a nested mobile IPv6 NEtwork MObility (NEMO) environment. We propose an adaptive scheme which can optimize the routing process of the data communication, and minimize the ...
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 ...
Joint mode selection, channel allocation and power assignment for green device-to-device communications
(
IEEE Computer Society
, 2014 , Conference Paper)
Device-to-Device (D2D) communication has emerged as a promising technique for improving capacity and reducing power consumption in wireless networks. Most existing works on D2D communications either targeted CDMA-based ...
