Designing the Future Internet
The Internet needs a redesign to better handle the many smart objects being connected to it, according to a Rutgers University professor.

Connecting many smart objects to the Internet will result in an enormous boost in online traffic, which Rutgers University professor Dipankar Raychaudhuri aims to make manageable by a network redesign.
The U.S. National Science Foundation (NSF) in 2010 launched a Future Internet Architecture initiative, and Raychaudhuri and colleagues proposed a "MobilityFirst" project, which won funding from the agency. Raychaudhuri says the project concentrates on migrating from the current Internet protocol to name-based routing, in which names represent people, mobile phones, Internet devices, small sensors, or any other Internet-connected objects.
The advantages of a MobilityFirst approach include more flexible services, improved security, support for mobility across many technologies, efficiency, and the capacity to handle large volumes of traffic and data. NSF expects the presence of about 50 billion smart objects by 2020, and 1 trillion sensors soon thereafter.
Raychaudhuri says this system requires fast and low-delay networks to guarantee timely receipt of data, and three MobilityFirst trials are planned or underway. One trial involves a satellite service company that will employ the system to deliver content closer to users, and the second will extend an Internet service provider's circuits to deliver mobile service. The third trial will focus on targeted emergency messaging in disaster recovery.
