SODA: 6TiSCH Open Data Action

International audienceIndustrial-grade performance of wireless networks has become a reality of the open Internet of Things through a low-power wireless technology called 6TiSCH. A standardization group of the same name within the Internet Engineering Task Force (IETF) has been working on a zero-configuration, IPv6-enabled solution applicable to industrial monitoring and control, smart building, home, city and agriculture. The base standardization work is virtually done. Before different stakeholders invest significant resources in developing and deploying 6TiSCH-based solutions, they need to have a certain level of assurance about whether the technology indeed meets their requirements. An unbiased performance benchmark of a standards-compliant 6TiSCH solution is therefore required by the industry, the research community and the standardization group. 6TiSCH Open Data Action (SODA) is a research project that will provide a 6TiSCH benchmark and open datasets in different industry-relevant scenarios. SODA will automate the experimentation on these scenarios so benchmarking can remain up-to-date with changes to the standards, and facilitate comparison with future technological developments, resulting in continuous delivery benchmarking. This paper introduces the SODA project and seeks community involvement on the definition of scenarios and Key Performance Indicators, and on the usage of the tools that will be provided

Performance Evaluation the 6top Protocol and Analysis of its Interplay with Routing

Wireless Sensor Networks (WSNs) will represent a crucial enabling technology to interconnect sensors and actuators in future smart cities. Since many applications will demand for reliable and low-latency communication, current standardization efforts are focusing in the definition of novel wireless standard architectures, e.g., the 6TiSCH architecture, to improve reliability and introduce support for quality of service. In this paper, we evaluate the performance of the 6TiSCH architecture during the initial network formation. Specifically, the performance of the 6top protocol, defined in 6TiSCH for distributed negotiation of resources, is evaluated. Simulations highlighted how the initial negotiation of resources is influenced by the routing protocol and the link-quality estimation mechanism adopted. The performance evaluation allowed to draw a set of guidelines for network configuration to guarantee the reliability of the initial allocation of resources
