Performance analysis of the IEEE 802.15.4e TSCH-CA algorithm under a non-ideal channel - 2020

Performance Analysis Of The Ieee 802.15.4e Tsch-Ca Algorithm Under A Non-Ideal Channel

Research Area:  Internet of Things


The TSCH Collision Avoidance (TSCH-CA) algorithm has been implemented by the IEEE 802.15.4e amendment to decrease the probability of repeated collisions in the packet retransmission in the Industrial Wireless Sensor Networks (IWSNs). This paper proposes a two-dimensional Markov chain model to evaluate the performances of the TSCH-CA algorithm when only shared links are used under non-ideal channel conditions. The accuracy of this model has been verified through Monte Carlo simulations. Based on the proposed model, the expressions of different performance metrics that include retransmission probability, data packet loss rate, reliability, energy consumption, normalised throughput and average access delay have been obtained. Furthermore, a comparative study between TSCH-CA and the unslotted CSMA-CA of IEEE 802.15.4 under a non-ideal channel has been provided. Numerical results reveal that the TSCH-CA performances are clearly affected by channel errors when using only shared links under a noisy environment.
