Abstract
this paper presents a hybrid technique for mitigating co-tier interference between Femtocell Access Points (FAPs). This technique combines indoor deployment and cluster-based resource allocation. This requires estimation of the number of femtocell access points and their deployment locations to achieve the optimum coverage and distributing the spectrum fairly across the resulting cluster in relation to the number of users. The cluster head is selected in relation to the number of neighbouring FAPs and the distance between FAPs. Our simulation results show that both the coverage and capacity are significantly increased, the outage probability is significantly reduced, and most importantly co-tier interference is mitigated.
