Stochastic geometric analysis of RIS aided wireless networks

This master thesis aims at investigating the improvement of performance brought by the use of reconfigurable impedance surfaces (RIS) in wireless networks using a stochastic geometry approach. To this point, different situations are analysed where the non line-of-sight link using the RIS can be used together with the line-of-sight link. The links are subject to path loss and Nakagami-m distributed small-scale fading. First, the possibility of using multiple RIS together is studied. Then, cases where the links can be blocked by obstacles are modelled and different association rules are compared. For both schemes, the metric of performance will be the coverage probability.
