The addition of these base stations extends the offered system capacity and coverage area of the network. This two network parameters nowadays becomes rather important to provide Quality of Service (QoS) for data-hungry applications. Femto base stations (FBS) are deployed randomly to extend the coverage of conventional base stations. Since the femtocells are operating here in open access mode, so that the handover probability parameter becomes important concern. In this article, we declare the handover probability using the fundamentals of stochastic geometry.

The benefit of using femtocells is the capacity and coverage extension capability. To fulfill strict Quality of Service (QoS) requirements in next generation mobile networks such as LTE (Long Term Evolution) or LTE-Advanced, capacity and coverage enhancing becomes rather important. On the other hand, adding small cells like femtocells next to macrocell modifies the interference pattern of the current region. Therefore the number of small cells in a given area should be limited. In this paper we provide an analytic framework to calculate the outage probability for a macrocell user in OFDM based femtocell networks when the deployed femto base stations are composing an independent Poisson cluster process (PCP) such as Thomas cluster process. Cluster based femtocell modeling offers accurate network planning for mobile operators. In this cluster based realization we give an interference characterization and consider the outage probability for a randomly deployed user when communication channel is infected with Rayleigh fading.

The novel solution makes use of geographic location information and previous records of access network parameters. The method exploits the benefits of multihomed mobility configurations by introducing a special handover execution protocol entirely based on flow bindings. Using actual location information and previously recorded context data, the system is able to predict handovers and proactively prepare itself for the appearance of access networks. We studied the performance of our proposal by implementing the framework and handover execution scheme in a real-life 3G/Wi Fi multi-access testbed environment, and showed that handover latency is almost totally eliminated. As our solution strongly relies on the prediction accuracy, we have also developed a probabilistic system model and evaluated of the probability of wrong positioning on the prediction raster.

OFDM-based air interfaces allow sharing this capacity in a very flexible way. MIMO transmitters and receivers introduce significant increase in capacity in exchange of very sophisticated signal processing algorithms. In this paper we present a new system model for OFDM-based LTE small cell systems which allows computing the overall system capacity when mobile MIMO users move along edges of a graph, e. g. roads.
