ResumoDirectional antenna has tremendous potential in improving the network capacity and anti-jamming compared with omni-directional antenna for ad hoc networks. In this article, a novel MAC protocol called TDPA based on TDMA was presented for ad hoc networks with directional antenna. It improved the spatial reuse by adaptively selecting interference-free angle according to communicating nodes positions, and increased the network throughput and broadcasting efficiency by piggyback retransmission technique. Analysis and simulation results showed that it can significantly improve network performance.
