Real-Time Enabled IEEE 802.15.4 Sensor Networks in Industrial Automation

Free registration required

Executive Summary

Sensor networks have been investigated in many scenarios and a good number of protocols have been developed. With the standardization of the IEEE 802.15.4 protocol, sensor networks became also an interesting topic in industrial automation. Here, the main focus is on real-time capabilities and reliability. The paper analyzed the IEEE 802.15.4 standard both in a simulation environment and analytically to figure out to which degree the standard fulfills these specific requirements. The results can be used for planning and deploying IEEE 802.15.4 based sensor networks with specific performance demands. Furthermore, the paper clearly identified specific protocol limitations that prevent its applicability for delay bounded real-time applications.
