摘要：Energy efficiency in cellular networks has been receiving significant attention in wirelesscommunication, because of the importance in reducing the energy consumption and maintaining the profitability ofnetworks, in addition it makes these networks “greener”. In the traditional cellular architecture, the urban celltopography increases the capacity along with the coverage require the deployment of a large number of base stations(BSs). This approach is cost prohibitive and also increase the mobile station (MS) transmission power. An alternative,relaying techniques are expected to alleviate the coverage problem and reduce the MS transmission power. To proposea geometrical model for the energy efficient relay station (RS) placement that requires only a small number ofcharacteristic distances and is to estimate the maximum cell coverage of a relay aided cell, given power constraints.This proposed method analyzes the path loss model based on RS to BS link and it compares both cell coverage andenergy efficiency using Decode and Forward (DF) relaying schemes in line of sight conditions.
