| 摘 要： | 提出一种用于Ad Hoc网络MAC层的多天线、多信道动态TDMA协议,它采用一个全向天线和多个方向性的扇区天线.该协议通过空分复用控制,可提高网络的吞吐量,通过基于动态时隙分配算法和相应的邻居发现策略,以减少时隙空闲,提高信道利用率.利用NS-2平台进行的仿真研究表明,与单一全向天线的MAC协议相比,所提出的协议在吞吐量和时延方面有明显的提高.

| Abstract: | A New Ad Hoc MAC protocol using multi-antenna and multi-channel is proposed in the paper.The protocol is supported by one omni-directional antenna and several sector antennas.The network throughput is improved by space division multiplex.The idle-time slot is reduced by dynamic time-slot allocation and neighbor discovery strategy.The simulation with NS-2 shows that the proposed protocol perfors much better than the protocol based on one omni-directional antenna in throughput and delay. |
