     47This video demonstrates that a Carrier Sense Multiple Access Collision Avoidance  (CSMA/CA) MAC protocol improves performance in a hidden node scenario. Two protocols are compared, a two-way handshake CSMA protocol and a four-way handshake CSMA/CA protocol. The two-way handshake CSMA protocol consists of a DATA-ACK exchange and the four-way handshake CSMA/CA protocol consists of an RTS-CTS-DATA-ACK exchange. The hidden node topology is implemented utilizing three [wiki:HardwareUsersGuides/FPGABoard_v1.2 WARP FPGA boards], three [wiki:HardwareUsersGuides/RadioBoard_v1.4 radio boards], and three [wiki:HardwareUsersGuides/ClockBoard_v1.0 clock boards].
