DualBlock: Adaptive Intra-Slot CSMA/CA for TSCH

“…In [31], the authors develop an analytical model based on a discrete time Markov chain for modelling the behaviour of IEEE 802.15.4e TSCH CSMA/CA algorithm by taking into account channel errors in industrial wireless sensor networks. In [32], the authors propose a stochastic model for performance analysis of TSCH networks for shared links with nonideal wireless link properties. The above works are used to derive network performance using shared links in TSCH networks, in terms of packet delivery ratio, packet latency, and energy consumption.…”

Approximated Pareto Analysis for Fast Optimization of Large IEEE 802.15.4 TSCH Networks

“…For each cluster in the network with a given configuration, we extract PEP hop , PL hop , and E hop using the TSCH performance model in [7]. Here, PEP, PL, and E represent the worst cases of reliability, latency, and energy consumption for a specific configuration of the network, respectively.…”

“…The first loop traverses over clusters from 1 to N CH , and the inner loop iterates over all possible configurations. The performance of the clusters for each configuration are derived using the performance model in [7] (line 13). If the performance provided by the cluster configuration does not meet the user's constraints, it is removed from the eligible configurations.…”

“…Recent studies such as [7], and [3] have shown that the selection of CSMA/CA MAC parameters of a TSCH network significantly influence the network performance. Therefore, it is very important to properly configure these parameters to get the best performance of the network operation both at designtime as well as at run-time.…”

TSCH Evaluation under Heterogeneous Mobile Scenarios

“…Several aspects of TSCH have been explored, such as energy consumption [10], scalability [9,11] and latency [12]. However, it is still unclear how a TSCH network performs under a mobile scenario since that topic is not explored thoroughly in the scientific literature.…”
