Impact of mobility on blocking in one-dimensional cellular networks with new call channel limiting scheme

We investigate the validity of the analytical model of new call channel limiting scheme (NCCL) by means of simulation. NCCL limits new calls to access the total channels with parameter a while handover calls have no restriction to access the channels. We focus on the effects of users´ mobility and the parameter a on the blocking probabilities of new and handover calls. We observe that the analytical model presents a good match to the simulation model for low mobility users whereas there exists a small disagreement for high mobility users. Furthermore, we find that the variability of mobile users´ velocity affects the applicability of the analytical model, in particular, for small α and light traffic. We extend the analytical model by including the influence of the distribution of mobile users´ velocity. We show that the extended analytical model yields better agreement with the simulation results.
