Decentralized Networking in White Space

There are several design challenges to make a decentralized white space wireless network work, such as signal interference and spectrum fragmentation. The goal of this project is to come up with technological solutions that would overcome the challenges.

Networking Over White Spaces (KNOWS)

In this MSR flagship project we developed devices, networking protocols, databases, and white space systems, which we demonstrated to policy makers worldwide, including the FCC, to help establish the white space rules. This project is ongoing since 2005.

Cognac: Cognitive Network Access
