Performance Evaluation of Orchestra Scheduling in Time Slotted Channel Hopping Networks

TL;DR

This paper evaluates how Orchestra scheduling impacts energy efficiency and recovery time in TSCH networks using RPL, especially during transient states like node failures.

Contribution

It provides a comparative analysis of energy consumption and network stability with and without Orchestra in TSCH networks during transient states.

Findings

Orchestra reduces energy consumption by up to one-third during transient states.

Orchestra helps the network recover faster to a stable RPL tree after node failure.

Energy efficiency improves significantly with Orchestra in low-power networks.

Abstract

In this paper, we evaluate the performance of networks that use RPL (Routing Protocols for Low Power and Lossy Networks) with TSCH (Time Slotted Channel Hopping) and Orchestra (an autonomous method for building the TSCH schedule). We measure the performance in the transient state when a node dies (i.e., removed from the network) and determine how long it takes for the network to come back to a stable RPL tree and also what the impact is with respect to energy consumption. Our analysis shows that the Orchestra reduces the energy consumption when the RPL is in a transient state, like in the case of when one of the nodes die. Furthermore, we calculate the energy consumption in the transient state without using Orchestra, and then we make a comparison between both outcomes. We show that Orchestra reduces energy consumption by up to one-third compared to not using Orchestra.
