Networks and Mobile Systems Group


The Networks and Mobile Systems (NMS) group at MIT's Lab for Computer Science conducts research in many areas of networking and mobile computing, with an emphasis on designing, implementing, and evaluating systems, protocols, and applications. Our mission is to prepare the next-generation of researchers and developers in these areas by investigating challenging, high-impact research projects. These projects span many areas, including network resource management and support for adaptive, communication-intensive applications; network architectures for specialized devices and domains (e.g., medical applications); wireless networking and support for mobile, location-dependent applications; and Internet protocols, applications, and performance. Current projects include:

Wireless & sensor networks
(1) SLAM: Scalable Location-Aware Monitoring is a scalable network architecture integrating millions of real-world sensors with actuators and distributed software applications; (2) The Patient-Centric Network project is developing a networking and systems infrastructure for future medical environments; and (3) The MECN project is developing a General Multiplexed ECN Channel (4) Several of our efforts contribute to Project Oxygen.

Overlay and P2P networking
(1) RON (Resilient Overlay Networks), an application-controlled robust routing architecture for improving the reliability and resilience of packet routing in the wide-area Internet; (2) Project IRIS is a multi-institution collaboration on designing the network and system infrastructure for resilient Internet services using distributed hash tables like Chord as overlay networks; and (3) Infranet is a system to circumvent Web censorship.

Internetworking
(1) Internet Analysis: Failure analysis using BGP and probe data; DNS analysis; (2) CM (Congestion Manager), an integrated end-to-end congestion management architecture for the future Internet. This includes several new adaptive applications, including VideoCM for Internet MPEG-4 delivery; and (3) XCP: Congestion Control for High Bandwidth-Delay Product Networks.
