Throughput and Delay Behaviour in ZigBee Wireless Sensor Networks

In terms of transmission range and data speeds, ZigBee technology bridges the gap between IEEE 802.11 WiFi and IEEE 802.15 Bluetooth standards and offers the architecture needed to support WSNs. ZigBee is typically categorized as a low-rate wireless PAN technology. WSNs based on ZigBee are utilized in many different applications. There are single and multiple coordinators and routers for each of the 24 sensors in the modelled system. Every sensor node is represented by a ZigBee endpoint, which sends signals to the ZigBee coordinator master node. Next, by connecting the system to the server via Ethernet LAN, the data can be accessed. A Riverbed (OPNET) Modeler Academic Edition 17.5 was used to conduct this simulation. In order to examine the performance of the four modelled WSNs, this paper analyses the system's performance in terms of throughput and delay. The findings demonstrated that both throughput and delay rise as the number of routers increases. Moreover, throughput and delay are unaffected by adding more coordinators.
