Cross layer design based green cellular architecture using stochastic optimization

Abstract

Cross layer techniques are in general used to enhance a network's performance. Various cross layer models have been proposed by researchers for energy efficient scenarios, but most of these models do not consider all the fundamental Quality of service requirements along with energy efficiency. Quality of Service and Queue Stability affect the energy consumption and network performance in each time slot of a network. So an adaptive model is necessary to guarantee the Quality of service and Queue stability along with reduced energy consumption. The model proposed in this paper uses the stochastic drift plus penalty method to improve energy efficiency along with Quality of Service and Queue stability constraints. The optimization technique in the proposed model does not require channel density function. The energy efficiency improvement under Quality of Service and Queue Stability constraint is demonstrated by simulation studies in the paper.
