Networking From the Rooftop
Mesh networks are maturing - Networking From the Rooftop: MIT researchers are developing new routing strategies for a wireless network that hops data in the roofs of the city.
Fun facts:
- The total cost of the equipment for each node is $685.
- Instead of finding the shortest path between two nodes, their protocols try to find the best path—the one in which data packets won’t get stuck or corrupted along the way. This requires a constant monitoring of the links.
- Another surprising phenomenon is the lack of symmetry in the link transmission quality: it is not uncommon for node A to be able to send data to node B easily, while node B can’t reciprocate. Such anomalies complicate the development of routing schemes.
