Poznan Area Buildings + Reachable Endpoints for Given RF Transmitter Location and Parameters, with and without RISs Installation.

1- The obstacles_save folder contains arrays defining the vertices locations (x,y) of buildings in the considered area in Poznan, Poland.

A transmitter is placed at the center of a square at location [645, 1125]. Possible receiver (or relay trasnceivers) locations are defined as the vertices (i.e., corners) of buildings (from previous list). The goal of the simulation is to find how many hops are needed to reach, if possible, each location from the previously mentioned list of vertices, assuming a maximum allowed path loss value of 80 dB between any two consecutive hops. 

2- The arrays in no_ris specify the vertices reachable within N sucessive hops, when no RIS is installed in the area.

3- Similarly, the arrays in single_ris give the coordinates of vertices reachable with N hops when a single RIS is installed in the square (as shown in related paper).

4- Same as (3) but for another RIS installation with another orientation in the same square.
