BLUE-INTEROP - Enabling BLUE Economy devices INTEROPerability through the JANUS standard

Access/Technology provider: NATO STO, T-LOON

End User: WSense Ltd, UK [Industry]

Dates: November 2020 - September 2021

Goals: This TNA addresses the challenge of interoperability in data exchange between heterogeneous assets which is currently one of the main bottlenecks for the development of effective cooperative underwater acoustic networks.

This project makes use of the WSENSE JANUS implementation and a set of JANUS applications developed by NATO STO, exploiting the NATO T-LOON testing infrastructure. The applicant used the T-LOON to collect acoustic and environmental data over a long time period, thus exploring different seasons and environmental conditions. This also allowed the applicant to have enough time to process the acquired data (in between experimental activities), thus modifying/tuning the execution of the experiments. Strict interaction between the applicant and NATO STO personnel was ensured to: 1) validate the provided signals and experimental requests; 2) verify the collected data; and 3) share the acquired data.

This project was led by WSENSE LTD (UK). The LOON was used to collect a large dataset of acoustic signals that will be used to test and validate the WSENSE software implementation of different types of modulation schemes in real channel conditions. The transmission of different modulation and coding schemes was explored, including low data rate single carrier modulation, such as PSK (phase-shift keying) and JANUS, and high data rate multicarrier modulations, such as OFDM (Orthogonal Frequency-Division Multiplexing) and chirp-based modulations. Additionally, using the collected dataset, the performance of the  WSENSE JANUS software was evaluated in scenarios with Doppler effects.
