This research developed a Zigbee mesh network topology to assess the data transmission efficiency utilizing the Ad-Hoc On-Demand Distance Vector (AODV) routing protocol. AODV is Zigbee's low-power, low-datarate wireless ad hoc network routing protocol. A physical mesh network was created using Zigbee components, namely the Zigbee Coordinator (ZC), Zigbee Router (ZR), and Zigbee End Device (ZED). Data transmission experiments were carried out among the Zigbee modules with the AODV routing protocol, and evaluated over four distinct versions. Modifications were made to key aspects of the AODV protocol, including mesh selfhealing and link cost management. The experimental results revealed that during the self-healing phase, all modules in the network were engaged, resulting in a transmission time of 0.4 seconds. After the direction was established, data was sent in only 0.01 seconds, achieving a speed that was 40 times faster than the previous experiment.
