SpyderMesh - A Dense Urban Wireless Mesh Network

20 nodes have been deployed across Prince George's Park Residences. The nodes are currently running the MIT Roofnet software.

SypderMesh is a multi-radio 802.11 a/b/g Wireless Mesh test-bed in development at NUS CIRL. There are currently 20 active nodes on the network, deployed at Prince George's Park Residences, a typical dense urban setting.

The nodes run the OpenWrt (OpenWrt, 2009) Linux distribution for embedded devices (SVN revision 12646). A typical installation image is about 6MB in size. Several packages essential to the operation of Roofnet were cross-compiled for the current hardware.

 1. Click Modular Router (Click, 2009) version 1.60 together with Roofnet extensions.

 2. DNSMasq DNS/DHCP server version 2.42 to provide network access to users.

 3. Dropbear SSH version 0.50 for remote access to and control of nodes.

 4. Jugi’s Traffic Generator (JTG, 2006) 1.95 to test network performance.

 5. Madwifi wireless driver (MadWifi, 2009) for Atheros chipsets, modified to enable sending and
    receiving of 802.11 frames from Click.
