Grid is a system for routing in wireless ad hoc mobile networks. Grid is developed by MIT LCS's Parallel and Distributed Operating Systems group. We've deployed Grid in two test-beds: a 29-node network in the LCS building, and a 50-node rooftop network with nodes in graduate students' apartments in Cambridge (shown at right). See the Roofnet homepage if you are interested in hosting a node for the outdoor network or want more information about that specific project. The Grid network software is publicly available as open source, see the software page.
The main focuses of our current work are:
- Finding high-throughput routes despite lossy radio links.
- Better MAC protocols for ad-hoc forwarding.
- Understanding potential system capacity and efficient spectrum use.
- Scalable ad-hoc routing protocols.
- Battery-friendly communication protocols.
- Geographic forwarding and distributed location databases.
- Secure forwarding despite misbehaving nodes.
