DARPA SPECTRUM CHALLENGE
The DARPA spectrum challenge was a competition help by DARPA in coordination with WINLAB. The challenge was to create an agile wireless communication protocol that would adapt to a changing wireless environment. Teams competes against each other to get the most packets through, and coordinated with one another to get the most combined packets across. WINLAB hosted the challenge, where we developed the infrastructure to conduct the challenge, configured the radio environment, and helped supported the teams competing.
