Welcome to Libmac

The libmac library is designed for the NSF ​ORBIT Testbed Project. it is a user-space C library that provides applications with an API for,

• Injection and capture of MAC layer frames.
• Manipulation of a subset of wireless interface parameters at both aggregate and per-frame granularity levels.
• Communication of a subset of wireless interface parameters from one end of a network connection to the other, on a per-frame granularity level.

Manipulation and communication of wireless interface parameters, was achieved by modifying open-source Linux device drivers for atheros and Intel a/b/g 802.11 cards.

The architecture diagram is shown below - Libmac uses open-source libraries ​libpcap, for frame capture and ​libnet, for frame injection.

Starting Points

For Experimenters

Currently supported linux device drivers in the libmac package include ipw2200(version 1.0.8) and madwifi
