Deployment and experimental verification for data communication in heterogeneous wireless networks

With the growing interest in various wireless networks, the need for seamless connection and interoperability of heterogeneous wireless networks is becoming increasingly important. In this research, we focus on deploying the heterogeneous wireless networks, which consists of Wi-Fi networks and ZigBee networks. In heterogeneous wireless networks, data communication between pair of a sensor node and a mesh node is essential, meaning that the sensor node may receive data from the Wi-Fi device, and vice versa. We conduct some experiments to test and verify the interoperability issues, i.e., the coexistence radio interference and addressing of the heterogeneous wireless networks. We also investigate the effect of background traffic on the performance of heterogeneous wireless networks. The results reveal that both round-trip delay and packet loss increase as the background traffic increases.
