Analytical Model for Mobile User Connectivity in Coexisting Femtocell/macrocell Networks
In this paper the authors investigate the performance of mobile user connectivity in femtocell/macrocell networks. The Femto User Equipment (FUE) can connect to Femto Access Point (FAP) with low communication range rather than higher communication range to Macro Base Station (MBS). Furthermore, in such emerging networks, the spatial reuse of resources is permissible and the transmission range can be decreased, then the probability of connectivity is high. Thereby in this study, they propose a tractable analytical model for the connectivity probability based on communication range and the mobility of mobile users in femtocell/macrocell networks. Further, they study the interplays between outage probability and spectral efficiency in such networks. Numerical results demonstrate the effectiveness of computing the connectivity probability in femtocell/macrocell networks.
