“…The impact of user mobility on cellular networks has been studied in several papers, for instance in [5]- [9]. In [5] a tutorial on mobility aware performance analysis of cellular networks and different user's mobility are present. In [6] the probability distribution function of the path length that a user will be associated with the same base station is derived.…”

This paper proposes novel and generalized expressions to characterize the performance of modern cellular networks under realistic user mobility behavior. The η-µ distribution is employed to derive the received power probability density function, the average bit error rate for different modulation schemes, and the coverage probability assuming a Poisson point process spatial distribution of base stations in downlink. The user is assumed to experience fading with Maximum Ratio Combining (MRC) and move according to a random way-point mobility model. To get more insights on the achivable diversity order, accurate asymptotic expressions for the coverage probability and average bit error rate are derived. The derived expressions are applicable to different widely-used fading environments, such as Rayleigh and Nakagami-m as particular cases, by an appropriate selection of the η-µ parameters. Monte Carlo simulation was used to show the validity of the proposed expressions. In addition, the generalized expressions allow the system designer to quantify the effects of user mobility on the cellular network performance, in different propagation environments, and network topologies as a function of the number of base stations and MRC branches.

“…However, with existing networks, these connections will be prone to frequent disruptions arising from insufficient support for high mobility broadband services. Improved mobility management (Imran et al, 2019a;Ozturk et al, 2019;Tabassum et al, 2019) and proactive handover (HO) optimization techniques (Ahmed and Alzahrani, 2019;Mollel et al, 2019;Mollel et al, 2020) are required for consistent quality of service along highways or speed train routes.…”

“…Cellular networks evolve from planned cells to irregularly dense multi-tier networks to satisfy the exponential growth of the wireless data traffic [45]. Many low power BSs are deployed in congested areas, such as shopping malls, stadiums, coffee shops, and etc, to enhance the network capacity and extend the coverage.…”

“…As it is obvious that the Wyner and grid models are not practicable for characterizing the SINR, stochastic geometry has proven to be a useful tool to quantify and model the interference and coverage probability in cellular networks which approximates the actual networks [45]. To provide insight into the operation of the networks, Poisson Point Processes (PPP) model is applied.…”

The rapid growth of small cells is driving cellular network toward randomness and heterogeneity. The multi-tier heterogeneous network (HetNet) addresses the massive connectivity demands of the emerging cellular networks. Cellular networks are usually modeled by placing each tier (e.g macro, pico and relay nodes) deterministically on a grid which ignores the spatial randomness of the nodes. Several works were idealized for not capturing the interference which is a major performance bottleneck. Overcoming such limitation by realistic models is much appreciated. Multi-tier relay cellular network is studied in this paper, In particular, we consider $${\mathscr {K}}$$ K -tier transmission modeled by factorial moment and stochastic geometry and compare it with a single-tier, traditional grid model and multi-antenna ultra-dense network (UDN) model to obtain tractable rate coverage and coverage probability. The locations of the relays, base stations, and users nodes are modeled as a Poisson Point Process. The results showed that the proposed model outperforms the traditional multi-antenna UDN model and its accuracy is confirmed to be similar to the traditional grid model. The obtained results from the proposed and comparable models demonstrate the effectiveness and analytical tractability to study the HetNet performance.
