**5.1 Zigbee network method**

The OPNET modeller is one of the most important simulation tools for communication network inspection. ZigBee networks are known for their low power consumption, low cost, low data rate, and high battery life.

The current work as shown in **Figure 12**, consists of the workstation featuring a coordinated connection to six routers, with eight nodes installed at a range (200 meters) from each other. To participate in the calculation of system variables, the OPNET collected a large number of variables. The indicators relate to two types of statistical data for the agreement: local and global statistics. However, in terms of network performance, this study is more occupied in collecting quantitative information for the system. As a result, current research is based on data obtained from global statistics [1].

The values of the design parameters are shown in **Figure 13**, and the values of the parameters on the router are shown in **Figure 14**. Transmission power is estimated to be 0.1 w.

The ZigBee coordinator parameter is illustrated in **Figure 15**.
