Worst-Case Bound Analysis for the Time-Critical MAC behaviors of IEEE 802.15.4e
Ref: CISTER-TR-170501 Publication Date: 31, May to 2, Jun, 2017Abstract:
With an advancement towards the paradigm of
Internet of Things (IoT), in which every device will be interconnected and communicating with each other, the field of wireless
sensor networks has helped to resolve an ever-growing demand
in meeting deadlines and reducing power consumption. Among
several standards that provide support for IoT, the recently
published IEEE 802.15.4e protocol is specifically designed to meet
the QoS requirements of industrial applications. IEEE 802.15.4e
provides five Medium-Access Control (MAC) behaviors, including
three that target time-critical applications: Deterministic and
Synchronous Multichannel Extension (DSME); Time Slotted
Channel Hopping (TSCH) and Low Latency Deterministic Network (LLDN). However, the standard and the literature do not
provide any worst-case bound analysis of these behaviors, thus
it is not possible to effectively predict their timing performance
in an application and accurately devise a network in accordance
to such constraints. This paper fills this gap by contributing
network models for the three time-critical MAC behaviors using
Network Calculus. These models allow deriving the worst-case
performance of the MAC behaviors in terms of delay and
buffering requirements. We then complement these results by
carrying out a thorough performance analysis of these MAC
behaviors by observing the impact of different parameters.
