“…Consequently channel hopping sequence determined by both ends of the link make more sense, in other words, links rather than either of the communicating sides alone should dictate the hopping sequence in A-TSCH. We term such link-associated blacklists as link-masks for distinction with the local blacklists of individual nodes, and the definition is given in equation (3).…”

“…Such a phenomenon poses a challenge to wireless sensor networks (WSNs) because of their constrained capacity to contend with more powerful equipment for scarce spectrum. The channel hopping technique addresses the coexistence issue [2], [3] through periodical switch of the communication frequency, which distributes the risk of encountering interference over all available channels [4]. The technique has been widely accepted [5], [6] and time slotted channel hopping (TSCH) is now part of the forthcoming IEEE 802.15.4e [7].…”

Abstract-The performance of wireless sensor networks (WSN) is prone to adverse influences from a number of factors such as the interference from co-located wireless systems utilising the same spectral space. Channel hopping technique was proposed to mitigate the problem via periodic change of the operating frequency, and has been adopted in the form of time slotted channel hopping (TSCH) by IEEE 802.15.4e standard. This paper proposes adaptive slotted channel hopping (A-TSCH), an enhanced version of the TSCH aided by blacklisting technique. Complete design and implementation specifics are provided; and the results of experiments are analysed to show its advantages over existing TSCH. The main finding of this work is that A-TSCH can significantly improve the reliability of channel hopping scheme and thus provide better protection from interference for wireless sensor networks.

Abstract-There is currently a rapid development of new types of wireless communication channels for industrial automation. This paper aims to provide some experimental data and theoretical justification on packet latency and packet loss for a wireless communication channel exposed to intentional radio interference. The intentional radio interference used in the experiments is an attempt to simulate possible future co-existence scenarios in a dense wireless communication environment at an industrial site. For the cases tested packet loses of less than 10% was obtained. Latency is shown to depend on channel access and will has a deterministic behaviour.

“…This poses a challenge as sensors have to compete with a variety of other devices for the scarce spectrum. Channel hopping technique was developed to mitigate this issue [2], [3] by regularly switching communication frequencies in a pseudo-random manner [4]. This approach has been widely adopted [5], [6] and is now part of the IEEE 802.15.4e standard [7].…”

Abstract-Wireless sensor networks (WSN) are one of the enabling technologies for the Internet of Things. Due to the restricted capability of sensor, the performance of WSN is sensitive to interference from nearby wireless devices utilizing the same band. The channel hopping technique is adopted by IEEE 802.15.4e standard to mitigate such adverse effect. In this paper we propose the Adaptive Time-slotted Channel Hopping (A-TSCH) framework which augments standard IEEE 802.15.4e channel hopping with mechanisms for learning the spectral condition and blacklisting. Complete design and implementation are provided, followed by analysis of experimental results. We discover that A-TSCH improves the packet delivery in the presence of interference from co-located devices, leading to substantially enhanced reliability of WSN based on IEEE 802.15.4e.
