This is an R&D research project of MIMO mesh network which consists of multiple relay nodes equipped with MIMO antenna to relay packets in a multi-hop manner. Based on investigation of MIMO transceiver design, resource allocation, node synchronization, network coding and cooperative relay, we established protocols for different layers of the mesh network and developed a demonstrator system. Through evaluation of transmission performance, we confirmed superiority of the proposed system to achieve a 6 times gain in achievable throughput and significant packet delay reduction in comparison with conventional multi-hop relay protocols based on CSMA/CA. We also proposed an adaptive wireless resource allocation scheme to maintain the effectiveness of the proposed system even in non-uniform network topology. In the demonstrator system, we realized two-way relay of graphic data, which is also a proof for the effectiveness of the proposed synchronization scheme. Furthermore, experiment results with a setup of 3 relay nodes in an indoor environment practically confirmed the superiority of two-way relay.

这是一个MIMO Mesh网络的研发项目，该网络由多个配备MIMO天线的中继节点组成，以多跳的方式转发分组。在对MIMO收发信机的设计、资源分配、节点同步、网络编码和协作中继等方面进行研究的基础上，制定了Mesh网络不同层次的协议，并开发了演示系统。通过对传输性能的评估，证实了该系统与传统的基于CSMA/CA的多跳中继协议相比，在可实现的吞吐量和分组时延方面都有明显的优势。我们还提出了一种自适应无线资源分配方案，即使在非均匀网络拓扑下也能保持所提出的系统的有效性。在演示系统中，我们实现了图形数据的双向传递，这也证明了所提出的同步方案的有效性。此外，在室内环境中设置3个中继节点的实验结果实际上证实了双向中继的优越性。
