Abstract
With the rapid growth of the number of base stations (BS), reducing energy consumption and enhancing the stations' energy efficiency (EE) have become important research topics as BSs are the primary energy consumers in cellular networks. BS consumes 100% power even during low-traffic periods. One promising way to reduce power consumption during such periods is to deactivate lightly loaded small cell base stations or switch them to hibernation without compromising the quality of service (QoS) demanded by users. In This paper, the BS sleep mode algorithm proposes to switch the BSs to sleep mode during low traffic periods of a BS. The process starts with predicting the traffic load of BS and identifying the low traffic periods. This predicted traffic load is further used to identify the number of BSs to be kept in on mode and sleep mode for a particular time period. The appropriate BS mode (on, sleep, standby or off). After switching the BS to the desired mode, the power consumption of the BS is calculated. The prediction of traffic load helps BS to avoid frequent switching in case of consecutive low traffic periods, further enhancing energy efficiency. With the proposed BS switching technique 27% reduction in power consumption is achieved. This proposed algorithm can work with dynamic traffic load variations, which will help reduce the power consumption of a small cell BS.
