Recently, several MAC protocols using directional antennas have been proposed for ad hoc networks, which are mainly evaluated by computer simulations. This paper develops a MAC protocol testbed called TRNC/ESPAR for ad hoc networks, which enables the evaluation of directional MAC protocols as well as omni-directional protocols. At first, we investigate the requirements for the testbed. Based on them, TRNC/ESPAR is designed to consist of ESPAR as a practical smart antenna, IEEE 802.15.4 as a wireless module, GPS and gyro modules to support a location dependant MAC. After describing the detail design, we investigate the basic performance of the testbed and implement CSMA/CA. Implementing one of directional MAC protocols with 4 nodes, DMAC shows that the protocol doubles the throughput compared with CSMA/CA because of SDMA effect but if the pair is too near DMAC throughput degraded in a real environment, which could not be found without the testbed.
