The purpose of this topic was to study the communication performance of IEEE 802.15.4 network in an industrial environment. IEEE 802.15.4 is a standard designed for short range and low data transmission rate wireless network, mainly found in many wireless sensor devices. These sensor networks are being used in various application areas and industry. However, the industrial environment contains numerous equipment generating electromagnetic waves or consuming frequency band 2.4GHz for their communication. These major factors affect to quality of IEEE 802.15.4 network, cause data loss during the transmission and reduce connection stability.
The study was carried out by conducting experiments in the Technobothnia laboratory where an industrial workplace was simulated. Two Digi XBee Radio Frequency (RF) modules were used to construct a simple IEEE 802.15.4 network where one module took a task of sending 1000 packets in a certain time period to the remaining module. Data was collected on the receiver side and analyzed for conclusions. By these characteristics, Python was used in this project to control XBee modules and visualize data.
Based on data gathered, the project shows how environment affects the IEEE 802.15.4 connection performance, monitors IEEE 802.15.4 network latency and concludes with data loss pattern in IEEE 802.15.4 transmission.
