Abstract

The growing number of users and macro base stations (BSs) in LTE-A network causes large amount of energy consumption for the whole network. In order to mitigate this problem, a sleep mode algorithm for Base Stations (BS) simultaneously powering Relay Stations (RS), deployed in the transmission area of selected BS considering the real time network traffic is proposed in this paper. The efficiency of power saving algorithms depends on an effective real-time network traffic detection and analysis. A method to detect and analyze real time mobile phone traffic in a cell is also proposed in this work. The number of Relay station to be deployed in the coverage area of a BS, transmission range and geographical areas to set up and factors for optimal deployment are also discussed in this paper considering the Qos parameter. Joint deployment of relay stations inter connected by X2 links and with the BS with the overlapped coverage is considered in this work. The deployment of Relay station inter- connected by X2 links and with the Base station also meets the strategies for efficient group Handoff. The performance is analyzed by comparing power consumption of BS with and without the proposed algorithm, the simulation results shows there is good power saving with this proposed method.
