IEEE 802.15.4e for IoT Applications: An OverviewSpeaker: Anis Koubaa – Riyadh, Saudi Arabia
Topic(s): Software Engineering and Programming
IEEE 802.15.4, was initially developed for coping with the requirements of low power and low data rate communication for wireless personal area networks, which then was adopted as a communication protocol for IoT applications. The IEEE 802.15.4 protocol was not able to cope with all requirements of IoT applications in terms of real-time, quality of service, and energy. Several add-ons were proposed to amend its behavior. To address its gap, the IEEE 802.154e protocol was proposed as an amendment to the legacy IEEE 802.15.4 protocol to better meet the requirements of IoT applications, mainly at the Medium Access Layer (MAC). It defines five different new behaviors each one tailored to particular design objectives and requirements based on the target applications, including AMCA, BLINK, DSME, TSCH, and LLDN. It also defines various enhancements to the original standard including multi-channel access, low latency and low energy, information elements, multi-purpose frames, enhanced beacons, fast association, group acknowledgement, and MAC performance metrics.
In this presentation, I provide a comprehensive coverage of the IEEE 802.15.4e, starting for the legacy standard IEEE 802.15.4. I will describe the different behaviors and the various enhanced mechanisms. Furthermore, I discuss the latest state of the art research works that analyzed gaps of the IEEE 802.15.4e and their solutions. I also present a performance analysis of the time critical MAC behaviors using Network Calculus. Current implementations and tools will also be presented.
