Directional beams can increase the spatial reuse of ad hoc networks, also the limited beamwidth decreases the mutual interference among transmitting signals, so, the performance and the anti-jamming ability are improved greatly. This paper analyzed the existent interferences in ad hoc networks, indicated corresponding methods, and proposed a scheme of using directional antennas. Supported by group mobility scenarios, detailed simulations and evaluations have been done, and results demonstrate the availability of the scheme
