Energy consumption in wireless communication system is rapidly increasing due to the growth in wireless multimedia access. Combating the adverse effects of excessive energy consumption demands for energy-aware system design called green communication, which has become the major focus of many researchers recently. In this paper, we propose user selection and power allocation schemes for a multi-user...
The growth in energy demand coupled with global warming provide new trends in communication systems known as green radio. The main focus in green radio is to provide new techniques to save energy consumption. In this paper, a new concept, named ultra wide time (UWT), is proposed to define the lower asymptotic consumed energy to transmit a given amount of information. With UWT concept, minimization...
Joint consideration of energy efficiency, multimedia quality and media authenticity has largely been overlooked in the studies of secure wireless multimedia streaming. In this paper, we propose an authentication - resource allocation framework for secure transmission of multimedia streaming over energy constrained wireless networks. The contributions of this research can be summarized in three aspects...
The decentralized power control problem in a generic wireless communication system can be seen as a competition between the communication nodes. In this paper, we formulate a new framework to the problem with the application of noncooperative game theory and opportunistic resource allocation concepts, where the satisfaction of Quality of Service (QoS) requirements is considered. Analytical and simulation...
Wireless communications systems have transmitter power control as an essential tool for managing radio resources. Decentralized power control is of special interest and may be characterized as a competition among the communication nodes. This indicates the adequacy of the application of noncooperative game theory concepts to the problem. In this work, we formulate a general framework to the distributed...
