Green Deployment Strategy for HetNets under Matern Hard Core Point Process

As one of the main pillars and the future trends of mobile communication technology, heterogeneous networks have received a lot of attention in the wireless industry. Explosive growth in mobile data traffic, leads to rapid increases in energy consumption of cellular networks. Improving energy efficiency by sleep operations of Base Stations (BS) may bring coverage holes. Hence the trade-off between energy efficiency and coverage performance is an important factor to be considered. This paper investigates on the impact of point processes on energy conservation of Het Nets (Heterogeneous cellular network) with guaranteed coverage. Fist, the relation between the average coverage probability and deployment parameters i. e, the BS density and transmission power is analysed by assuming Poisson Point Process (PPP) and Matern Hard Core Point Process (MHCPP). The analysis can lead to a optimal green deployment framework. The existing optimal green deployment strategy is based on a poisson distribution. The comparison of the stationary processes performance over the green deployment strategy shows that compared with a poisson distributed, heterogeneous network deployment, MHCPP distributed hetnet has slight improvement in system energy consumption reduction with sufficient coverage performance, and it incorporate dependence between deployment points as encountered in practice.
