The elusive capacity of networks
Calculating the total capacity of a data network is a notoriously difficult problem, but information theorists are beginning to make some headway.
Secure, synchronized, social TV
A technique called network coding could protect users’ privacy and providers’ content while making communications networks more efficient.
Explained: Ad hoc networks
Decentralized wireless networks could have applications in distributed sensing and robotics and maybe even personal communications.
Rethinking networking
MIT researchers helped develop a theory that promised much more efficient data networks; then they were the first to put it into practice.
The power of ‘random’
A ‘seemingly loopy’ technique that MIT researchers helped develop could dramatically improve the efficiency of communications networks.
