Using Adjacent Data Retransmission to Improve the Transmission Efficiency of Multi-hop Relay Networks

Data transmission systems are widely used in various aspects of life, industry, research and other fields. Transmission systems have different characteristics for different application scenarios. Many of them require multi-hop transmission to extend the transmission range, such as Wireless Mesh Network (WMN), Mobile Ad-hoc Network (MANET), Wireless Sensor Networks (WSN) and so on. The biggest problem of multi-hop transmission lies in that packet loss caused by bit error ratio (BER) in multiple transmission processes increases greatly, which makes end-to-end transmission reliability and bandwidth utilization decrease. This paper analyzes the impact of BER on bandwidth utilization in multi-hop relay transmission and proposes a simple and flexible transmission mechanism that is generally applicable to multi-hop transmission scenarios.
