Abstract :
IEEE 802.15.4 is a useful standard for wireless factory communication. Based on it, we give several solutions for cyclic data and non-cyclic data transfer, among which GTS (guaranteed time slot) can be assigned while a device requiring dedicated bandwidth or low-latency. But the control process for GTS is so complicated that the performance is degraded in applications. In this paper, the problems caused by GTS management in cyclic data transfer are analyzed and a GTS pre-allocation in such situation is proposed. Then we give the optimized solutions for field device communication which have better performance of simple control, lower jitter, less latencies and the minimum modification to the standard
