Performance Analysis of IEEE 802.15.4 Contention Free Period through Real-Time Industrial Maintenance Applications

Nowadays, a growing number of societies are looking for industrial wireless network solutions. However, industrial communications induce real-time constraints and those networks should at least fulfil those requirements. In this paper, we study IEEE 802.15.4 performances in order to support real-time traffic. This analysis brings out some limitations of that standard concerning cycle duration and amount of messages per cycle.
