Abstract

We propose a dynamic interference mitigation technique by incorporating cognitive capability and cooperative mechanism in two tier heterogeneous network (HetNet) with open access femtocells. To further enhance protection of victim user that is subject to interference, a cooperative mechanism is designed based on received power of user. We exploit stochastic geometry for modelling and analysing the effect of our interference mitigation mechanism in two-tier HetNet by considering Rayleigh fading environment. Results show significant improvement on the coverage probability.
