Improving network formation in IEEE 802.15.4e DSME

Abstract

Wireless Sensor and Actuator Networks are becoming attractive also for industrial applications, since recent standardization efforts have introduced significant improvement to reliability and deterministic communication delays. In this context, IEEE 802.15.4e is widely considered the major improvement, introducing many enhancements to the original IEEE 802.15.4 standard aimed at supporting critical applications. Among the new defined MAC protocols, Deterministic and Synchronous Multi-channel Extension (DSME) represents the most suitable option for applications with time-varying requirements. In this paper, an analysis of the IEEE 802.15.4 DSME MAC protocol during network formation is presented. The goal is to study the protocol performance and propose solutions to reduce the network formation time, improving energy and resource efficiency. To carry out the performance evaluation, DSME has been fully implemented in Contiki OS, an actual operating system for sensor nodes. The study has highlighted issues and inefficiencies in the network formation process, allowing to consequently propose effective solutions. In particular, it is proposed a set of guidelines for DSME configuration to the original MAC protocol that are proved to increase significantly the network formation efficiency

Data Management in Industry 4.0: State of the Art and Open Challenges

“…This part of research includes a great number of works on the M2M communication technological enabler, and more specifically concentrated on three of the main 802.15.4e MAC operation modes, Time Slotted Channel Hopping (TSCH), Deterministic and Synchronous Multi-channel Extension (DSME) and Low Latency Deterministic Network (LLDN) (for more details on the functions of those modes, the reader can consult [28]). Regarding the TSCH mode, the main research focus has been recently placed on synchronization, with some techniques using learning and prediction data from neighboring nodes [223], and other techniques using mutual synchronization of [223], [233], [237], [244], [250] IEEE 802.11(a/n) [230], [234], [236], [240], [241], [251], [ [246] distributed nodes [237], as well as on fast network joining algorithms [250]. Regarding the DSME mode, improved network formation has been studied in [244].…”

Regarding the LLDN mode, significant efforts have been invested in transforming the standard compatible for ultra-low latency applications, where the critical data need to be delivered with high reliability [233].…”

Sending multiple packets per guaranteed time slot in IEEE 802.15.4 DSME: Analysis and evaluation

“…Vallati et al performed simulations by using the network simulator Cooja to analyze the GTS allocation process. 7 Their work aims to select CSMA/CA parameters that minimize the number of contention access periods to complete the network setup procedure. The DSME implementation used in their analysis delivers four packets per GTS.…”
