基于Mesh的电力无线多跳高效传输技术研究

针对电力无线通信网络多跳传输不可靠的问题，提出了一种基于Mesh的免重传的多跳高效传输技术.该技术在源节点、接收节点之间布设备份节点，设计全新的免重传协议，使得所有节点根据监听/接收到的ACK/NACK信息自动识别自己的下一步状态，从而在不增加任何网络信令开销的情况下，有效降低了每个数据块的平均传输总次数，提升了电力无线通信网络的深覆盖、低时延、高可靠的业务传输能力.最后通过仿真计算得出，随着误块率的增大，免重传多跳高效传输技术的平均传输总次数较传统方案得到了明显改善，即明显降低平均端到端时延，具有很好的实际应用价值.

Efficient multi-hop transmission for power wireless network based on mesh

With regard to the issue of unreliable multi-hop transmission in power wireless communication networks,this article proposes a retransmission-free multi-hop efficient transmission scheme based on mesh.This solution distributes device nodes between the source node and the receiving node,and designs a retransmission-free protocol,so that all nodes can automatically identify their next state based on the listened/received ACK/NACK information.The proposed method can reduce the average total number of transmissions of each data block effectively with no adding of network signaling,and improve the power wireless communication network in aspects of deep coverage,low latency,and highly reliable service transmission capabilities.Finally,it is proved through theoretical simulations that with the increase of the block error rate,the average total number of transmissions of this scheme has been significantly improved compared with traditional scheme,which effectively reduces the end-to-end average transmission time,thus the proposed scheme has good practical application prospect.
