摘要: 多输入多输出(Multiple-Input Multiple-Output,MIMO)技术是能够实现多包接收(Multi-Packet Reception,MPR)功能。提出MIMO系统的MAC协议,该协议基于数据流控制方法实现多包接收功能,并在同一通信领域内支持多对一和并行通信。网络仿真中采用调用信道模型的方法,并利用OPNET和MATLAB进行了PHY/MAC跨层动静态联合仿真分析。仿真结果表明,所提协议能够有效地提高移动Ad Hoc网络吞吐量、端到端分组延迟等性能。

Abstract: MIMO systems are indeed a means of performing multi-packet reception, which can provide extremely high spectral efficiencies and system capacity. Based on data stream control method, a new MIMO MAC protocol is designed for Ad Hoc networks to support MPR and several to one communications. Making use of channel model, the protocol is evaluated by PHY/MAC cross-layer dynamic and static unite simulation in OPNET and MATLAB environment. The performance results show that the proposed can fully realize MPR and improve network throughput and delay.
