The radio grid emulator (as shown in Fig. 2) currently
consists of 64 wireless nodes having 802.11a/b/g wireless cards
laid out in a 8x8 grid with ~1m spacing between nodes. Each
node is connected via multiple high-speed Ethernet links for
transfer of applications, control and management information.
The system will be extended to 20x20 radio nodes in the next
phase of work. Users can have full access to the radio nodes
used in their experiments, download and run their own OS
image and software packages, control and reboot the nodes, as
well as access node console and console logs.
