An Efficient Base Station Sleeping Configuration for Ultra-dense Networks

With the exponential growth in demand by sub-scribers, ultra-dense networks (UDN) has shown to be effective in providing a high data rate. However, this excessive and random deployment of base stations (BSs) has escalated energy consumption and inter-cell interference. Base Station Sleeping (BSS) can significantly scale down the energy consumption by BSs during the underutilized period. To tackle this, a BSS configuration is proposed by keeping account of the UDN deployment scenario and users present per small cell BS (SBS). The proposed configuration is compared in terms of the overall downlink rate with the random configuration of BSS in UDN. Through extensive simulations, a trade-off is observed among downlink rate, Fairness index, and Energy saved.
