A near-optimal LLR based cooperative spectrum sensing scheme for CRAHNs
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In Cognitive Radio Ad Hoc Networks (CRAHNs), cooperative spectrum sensing schemes exploit spatial diversity of the Secondary Users (SUs), to reliably detect an unoccupied licensed spectrum. Soft energy combining schemes ...
Joint user-channel assignment for efficient use of renewable energy in hybrid powered communication systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we introduce a new green resource allocation problem using hybrid powering of the communication system from renewable and non-renewable sources. The objective is to efficiently allocate the power delivered ...
Incentive scheduler algorithm for cooperation and coverage extension in wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
In this paper, we focus on wireless coverage extension and nodes' cooperation. We propose a new protocol based on an incentive approach and a scheduling algorithm to reward cooperative nodes. The cost of cooperation can ...
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. ...
Exploiting 4G mobile user cooperation for energy conservation: Challenges and opportunities
(2013 , Article)
Recent years have witnessed tremendous success and popularity of mobile applications and services, resulting in an explosive growth in the number of mobile devices, as well as in the range and types of things these devices ...
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 ...
Enhancing spectral-energy efficiency for LTE-Advanced heterogeneous networks: A users social pattern perspective
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article Review)
The development of LTE-Advanced and beyond cellular networks is expected to offer considerably higher data rates than the existing 3G networks. Among the many potential technologies in LTE-Advanced systems, users' ...
Energy-aware rate and description allocation optimized video streaming for mobile D2D communications
(
Institute of Electrical and Electronics Engineers Inc.
