Modeling and Optimization of DSME-Guaranteed Time Slot Allocation in IEEE 802.15.4e Networks based on Traffic Model

The advancement in Internet of Things (IoT) technology has gained more interest for the development of smart technologies. Intuitively, a wireless sensor networks (WSN) enabled with low-rate data communication can be employed in smart technologies. However, the WSN employed for these technologies should meet the basic requirement for efficient communication among the nodes. The IEEE 802.15.4e standard operating in Deterministic and synchronous multichannel extension (DSME) mode can be adopted in WSN to enable multichannel data communication between the nodes. In this paper, an optimized DSME-guaranteed timeslot allocation (GTS) allocation algorithm is developed for WSN depending on the requirements such as bandwidth, delay, throughput, and network traffic. Furthermore, the algorithm is analyzed with performance parameters associated with the WSN. Finally, the proposed model is simulated using MATLAB 2023a programming tool.
