基于MIMO技术的WMNMAC协议研究

Research on WMN MAC Protocols Based on MIMO Technology

分析了MIMO技术中由于通信链路间干扰导致网络吞吐量降低的问题,提出了一种基于多模多信道技术的改进MAC协议(MPRP-MAC),利用节点中的多个通信模块以及多个正交信道资源,使节点可以在无干扰的情况下实现接收与发送同时进行。实验结果表明,该技术可充分利用天线资源,有效提高系统容量。

The degradation problem of network throughput caused by the interference between communication links with the MIMO technology is analyzed, and an improved MAC protocol （MPRP-MAC） based on the multi-radio multi-channel technology is proposed in the paper. The node can transmit and receive simultaneously under the condition of no interference using the multiple communication modules in the node and multiple resources of orthogonal channel. The experimental results show that the technology can make full use of antenna resources and improve the capacity of the system.
