Downlink coverage and average cell load of M2M and H2H in ultra-dense networks

In this paper, we study the impact of the coexistence of Machine-to-Machine (M2M) communication and Human-to-Human (H2H) communication on the network performance in Ultra-Dense Networks (UDNs). The performance evaluation of the network considers the downlink coverage, the average cell load of H2H users and the average uplink cell load of M2M devices. Using tools from stochastic geometry, we develop tractable expressions for the considered performance metrics. Furthermore, we investigate two association schemes to address the severe interference in UDNs, namely, connect to closest (de) base station and connect to active (CIA) base station. Considering the distinguishing features of UDNs, we model the path loss by a Stretched Exponential Path Loss (SEPL) model to address the close proximity of users to the base stations (BSs) and the high probability of Line-of-Sight (LOS) transmission as well. The simulation results show an accurate match with the analytical results. The network coverage significantly improves in C2A association scheme with no impact on the average cell load of H2H users. On the other hand, the average uplink cell load of M2M devices increases in C2A association.
