Patents are important steps in the process of transferring technology to marketplace. Patent creation has strong implications for the Institute: patents are incentives for their creators, as they imply recognition for their creativity and material reward when these inventions are marketable. These incentives encourage innovation, the guarantee to the continuous improvement in the quality of research and, ultimately, of human life. It is Institute IMDEA Networks’ policy to share a very high percentage of financial proceeds with inventors (our researchers) as reward for their excellence and hard work.

Announcement of Patent Filing for energy efficiency of computer networks
Institute IMDEA Networks, in collaboration with NEC Laboratories Europe and University Carlos III of Madrid, has announced the filing of a patent application. It establishes a novel method for the reduction of the energy consumption of a network by minimizing the number of active nodes involved in any given communication.
The importance of energy saving solutions for networking has steadily increased over the last few years due to environmental and economic reasons. In order to reduce the energy footprint of current and future systems, engineers are now working on enhancements to all networking layers with the objective of optimizing their energy efficiency. While some optimizations focus on energy saving while the network is operative, other approaches consider solutions which aim at minimizing the number of active nodes within the network.
The new proposed mechanism to reduce the energy consumption of the network is elegantly simple, both in design and application. For a given network topology and traffic matrix, it produces optimal routing in terms of energy and throughput, by providing a routing system which maximizes the number of flows that can be admitted into the network while powering down (fully or partially) nodes that are not required to transport the given traffic.
This mechanism has been shown to produce excellent results in different tests, outperforming other approaches very substantially in terms of throughput as well as energy consumption. The reductions achieved correspond to up to 40% of the amount of energy consumed.
This patent filing is one of the results achieved by the European Project CARMEN, concluded in early 2011, with outstanding grades. CARMEN focused on the provision of carrier-grade services over wireless mesh networks. Manufacturers, operators, universities and research institutes worked on the design of next generation multi-hop networks, comprised of heterogeneous radio technologies, meaning more available, easier-to-deploy and more cost-effective services.
