Abstract：A dynamic media access control protocol named DAND-MAC (Directional Antenna Neighbor Discovery and Media Access Control) is presented,which is designed to operate in the link layer of Mobile Ad-hoc Networks(MANETs) based on directional antenna.Omnidirectional antenna and directional antenna can operate synchronously with the unified scheduling of this protocol.Omnidirectional antenna takes the charge of topology and neighbor discovery,while directional antenna processes to build the link and the transmit data.This paper describes the system structure,key techniques of DAND-MAC.The simulations are operated with OPNET Modeler.The simulation results show that the performance of DAND-MAC could increase significantly in end-to-end delay,throughput and the reusability of time slots,comparing with traditional static time slot allocation and dynamic time slot allocation based on omnidirectional antenna.
