DASH7: Context Aware Sensor and Actuator Data Propagation System Using Sub-1 Ghz

Speaker: Maarten Weyn

Maarten Weyn received his Ph.D. in Computer Science on the topic of Opportunistic Seamless Localization from the University of Antwerp, Belgium. He is an Assistant Professor at the University of Antwerp, currently teaching the 3rd year bachelor courses Probabilistic Robotics and Mobile Communication  and Master courses Digital Communication, Real Time Locating System and Ambient Intelligence in the department of Applied Sciences: Electronics-ICT. He is the co-founder of the spin-off AtSharp, director of the Dash7 Alliance and IARIA Fellow.

His research focuses on sensor processing, ultra-low power sensor communication and localization.

Abstract:

The DASH7 Alliance Protocol originates from the ISO/IEC 18000-7 standard, but is enhanced to become an ultra-low power, long range, wireless sensor communication standard. The Dash7 Alliance is working on the expansion of the air interface to all sub-GHz ISM/SRD bands and tries to evolve to an independent Open Standard for wireless sensor communication. In contrast to other wireless communication protocols,
the DASH7 Alliance Protocol defines the full OSI stack including the file system. In the latest version of the protocol – designed in 2014 – automatic notification based on file changes are included which enables the developer to focus on sensor and actuator data processing, while the DASH7 stack handles the communication based on the values of these data. The University of Antwerp developed an open source stack which has become the reference implementation for the alliance for prototyping.
