Goals: This TNA proposes to use the NATO STO T-LOON testbed, extended with additional assets (additional nodes), to test and validate JANUS enabled networks, as well as JANUS networks applications. This project requested for 5 days of on-site access to experiment with the NATO STO testbed. Due to COVID19 restriction, it was not possible to execute the experimental activities on-site. To ensure the execution of this TNA project, the applicant and NATO STO worked together to organize and perform remote experimental activities. This required additional IT solutions and effort by NATO STO personnel to execute all the planned tests and acquire the required data. Multiple signals were transmitted and recorded under different environmental conditions. Various experimental configurations (single transmitter and concurrent transmitters) were explored, according to the requests of the applicant. Strict interaction between the applicant and NATO STO personnel was ensured to:
- 1) plan the new experimental activities;
- 2) validate the provided signals and experimental requests;
- 3) verify the collected data; and 4) share the acquired data.
This project was led by WSENSE LTD (UK). In this project a Jamming signal was designed for avoiding the correct decoding of JANUS packets. During this project the effectiveness of the Jammer was characterized by exploiting different transmission configurations such as the transmitted power by the source and the Jammer, the distance of the Jammer from the source and the receiver, the time delay performing the Jamming attack and different Jamming signals. As a possible countermeasure, a localization technique was investigated that could be adopted for reacting against a Jamming attack. By exploiting the time delay between the superimposed signal, injected by the Jammer, and those sent by the honest source it was possible to localize the Jammer.
The results will be disseminated as follows:
The channels impulse responses will be used to provide data for PhD and master students working on the topic at ISEN Brest.
Results on adaptive algorithms will be further developed and submitted for publication in scientific journals and conferences.
The possibility of sharing the results with the community, in particular with the team who has developed the Watermark test bench, is under study.
