2 Network Topology

A total of 75 Zigbee nodes were used to create the Z-Stack large mesh network test, consisting of one coordinator (ZC), 12 routers (ZR), and 62 end devices (ZED). Half of the devices use LAUNCHXL-CC26X2R1(5) hardware, whereas, the other half consist of LAUNCHXL-CC1352P(6), all using default output transmit power (5 and 20 dBm, accordingly). For a simple visual of the setup, see Figure 1.

Although all within radio proximity, the routing devices are evenly separated into six separate zones (2 ZR per zone), with the ZC in zone 1 and each zone only capable of communicating with the members of the adjacent zones. This is to ensure that a maximum of five hops (from zone 6 to zone 1) are analyzed during the test. The same was initially done with the end devices (twelve ZED per zone), however, these children would occasionally transfer zones while changing parents during execution of the test.
