Background/Objectives: We have proposed an improved algorithm for the delay sensitive networks with bulk periodic data traffic. This kind of networks such as Industrial networks that should transfer the monitoring data has a high sensitivity to delay since these networks should work real-time. Methods/Statistical Analysis: Considering and studying the industrial network traffic model, a new adaptive centralized GTS scheduling algorithm is proposed focusing on real-time communication and reliability which are two important issues in industrial wireless communication. Findings: Wireless Sensor Network (WSN) is selected for implementing the industrial network. Industrial Wireless Sensor Network (IWSN) and IEEE802.15.4 standard is the most popular standard for WSN MAC layer protocol. In this paper considering the industrial network data types new GTS scheduling scheme for IEEE802.15.4 is introduced for the delay sensitive networks with bulk periodic data traffic. Applications/Improvements: Our proposed algorithm by adapting the characteristics of industrial networks and IEEE802.15.4 standard shows high gain in delay improvement.
