Outage Probability Reduction Using Power Control in Heterogeneous Cellular Networks

In this paper, we have proposed a distributed power control algorithm to reduce interference and then outage probability in a heterogeneous cellular network based on Poisson point process (PPP) model. For adjusting the power, we have considered m tier outage probability that introduces outage probability for macro user located on origin and femto BSs creates interference for him. Our study has done on network with K-tiers being modeled as independent Poisson point processes. Simulation results confirm the mitigation of outage probability using proposed power control algorithm in this model
