Power consumption evaluation in a wireless MAN using cooperative diversity when both sources and relays are randomly located
Article No.: 8, Pages 1 - 6
Abstract
Most previous work on cooperative cellular networks has considered homogeneous relaying architectures where all nodes act as both sources and relays or considered heterogeneous relaying architecture where relays are fixed. In this paper, we examine the power consumption performance of heterogeneous cooperative cellular networks with two classes of nodes: source nodes (subscriber stations, SS's) that do not act as relays, and relaying agents (relays station, RS) that are dedicated to relaying functions with little concern about power consumption. In this architecture, source nodes are able to reap the benefits of cooperative communication, such as improvements in the achievable data rate and reductions in the transmit power, while reducing the overall power consumption since they do not act as a relay. We consider a geometry of a cell. Then we consider random locations of SS and RS, respectively, to analyze the average power consumption over the region of interest under the assumption that the SS and RS are distributed uniformly over the cell region.
