A hardware test bed for measuring IEEE 802.11g distribution coordination function performance
This extended abstract describes our experiences from constructing the MIT Roofnet, an experimental rooftop wireless network. The ultimate goal of Roofnet is to build an ad-hoc network infrastructure capable of providing pervasive highspeed network access. Currently, the network currently consists of more than 35 nodes spread over two square kilometers of Cambridge, MA. The network is self-configuring, robust in the face of varying link conditions, and automatically finds high throughput paths in the system. The main focus of this paper is on lessons we’ve learned about building and deploying this kind of system, though we will touch on some research results as well.
