Power consumption and spectrum usage paradigms in cooperative wireless networks: The way out of the energy trap!

Abstract

One of the most important and challenging topics for future wireless communications is the power consumption of wireless and mobile handheld devices. In Chapter 14 we underlined the importance of this issue and predicted that future terminals will consume even more power. The dramatic increase of power consumption can ultimately be attributed to the emergence of advanced services and it may result in an energy trap following the linear extension approach for future wireless communication systems. Therefore we address the problem of increased power consumption and introduce some solutions. In Chapter 18 the power consumption is also considered and solutions are given by means of task splitting in cooperative networks. Here we focus on the power that is consumed in the wireless transmission and reception process. Once more we advocate the use of cooperation, but this time the target is to reduce the power consumption for the receiving process of multicast services. The potential power saving using cooperation is not limited to multicast services, but they are used in this chapter for illustrative purposes. © 2006 Springer. All Rights Reserved.
