An Exact Scheduling Algorithm for Convergecast and Broadcast in Tree Topology WSNs -An Application to DSME-IEEE 802.15.4e
Original language description
Convergecast and broadcast operations in WSN based applications impose demands in terms of energy efficiency, reliability, and timeliness QoS properties which existing protocols struggle to fulfill. The Deterministic Synchronous Multi-channel Extension (DSME) mechanism introduced in the IEEE 802.15.4e standard constitutes a promising solution to address these strin gent QoS requirements, by enabling significant enhancements to the legacy IEEE 802.15.4 protocol, such as multi-channel communications, reduction of the Contention-Access Period, and group acknowledgments. However, the DSME-IEEE 802.15.4e standards do not propose a mechanism to build a traffic-aware schedule that assigns a frequency channel and time-slots to each transmission. Therefore, in this paper, we show how to configure the DSME parameters for the convergecast and broadcast opera tions while having in mind the above-mentioned QoS properties. In that direction, we propose an exact traffic-aware scheduling algorithm, based on Integer Linear Programming (ILP), that enables the system designers to optimize the configuration of all the required parameters of the DSME-IEEE 802.15.4e so that QoS requirements are met.
