[Discuss-gnuradio] 8-node USRP network with PHY Network Coding and Distr

Hi All,

As part of a recently completed EU collaborative FP7 project called Dense Cooperate Wireless Networks (DIWINE - http://diwine-project.eu/public/) we have developed an 8-node N210 network spread over a large office space demonstrating PHY network coding and distributed synchronisation. The abstract for the project is:

“DIWINE considers wireless communication in a dense relay / node scenario where WNC (Wireless Network Coding) messages are flooded via dense massively air-interacting nodes in the self-contained cloud while the PHY air-interface between the terminals (sources / destinations) and the cloud is simple and uniform. A complex infrastructure cloud creates an equivalent air-interface to the terminal, which is as simple as possible. Source and destination air-interfaces are completely blind to the cloud network structure. The cloud has its own self-contained organising and processing capability.

This concept facilitates energy-efficient, high-throughput and low-latency network communication performed directly at the PHY layer, which is capable of operating in complicated, dense, randomly defined network topologies and domains. The applications of the DIWINE paradigm are generic, being relevant to complex systems ranging from intelligent transport systems to healthcare and even machine-type communication in wireless networks.

However, in order to exhibit practical, highly focused and high impact results, DIWINE concentrates on two core application / demonstration cases: (i) smart metering networks and (ii) critical industrial monitoring and control applications. To this end, DIWINE algorithms and theoretical technology will be integrated into two industrial proof-of-concept demonstration platforms targeting the aforementioned applications. Both of these applications require low-latency, dense networking solutions and are sure to be integral to future European policy and society as evidenced by recent European Commission initiatives such as EUROPE 2020.”

The final demonstrator report is at http://diwine-project.eu/public/content/files/public/DIWINE_D5.42.pdf, please get in touch if you are interested in any of the theory or practice therein. One of the key features we used was to enable deployed MATLAB code (compiled shared libraries) so be called directly from C++ GR blocks allowing rapid prototyping. A manual of how to achieve this is currently being tested and I will post this ASAP.

Regards,

David
