  Abstract

Cell zooming is a technique that targets the traffic balancing and energy efficiency of the cellular network by adjusting the transmit power of the base station. In this paper, we propose a new cell zooming and sleeping algorithm in Poisson Voronoi Tessellation (PVT) random cellular network to improve outage performance. The proposed algorithm operates in a base station-centric distributed manner and requires only small amount of network state information to operate. Base stations classify the state information according to the quality of service provided to their user, and apply the cell zooming and sleeping based on information exchanged between adjacent base stations. Simulation results show that the proposed algorithm reduces the outage event. There exists a tradeoff between the outage reduction performance and energy efficiency but the algorithm still achieves at least 50% of outage reduction performance when there is no energy efficiency loss.
