SYN-DMAC: a directional MAC protocol for ad hoc networks with synchronization

Directional antenna has received intensive research interests in recent years due to its potential to increase communication efficiency and resilience to interference and jamming. In this paper, we provide a novel directional MAC protocol termed SYN-DMAC for ad hoc networks with synchronization. We demonstrate our proposed SYN-DMAC can efficiently address the major open problems in the directional MAC design such as the deafness problem, the hidden terminal problem, the exposed terminal problem and the head-of-line (HOL) blocking problem. Preliminary simulation results show that our scheme significantly improves throughput in comparison with IEEE 802.11 MAC protocol
