利用相邻数据重传提高多跳中继网络的传输效率

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

Xuesong Liu, Jie Wu, Meng Zhou

摘要:

数据传输系统广泛应用于生活、工业、科研等领域的各个方面。对于不同的应用场景,传输系统具有不同的特性。无线网状网(WMN)、移动自组织网络(MANET)、无线传感器网络(WSN)等都需要多跳传输来扩展传输范围,多跳传输的最大问题在于多个传输过程中误码率(BER)引起的丢包率大大增加,使得端到端传输可靠性和带宽利用率下降。分析了多跳中继传输中误码率对带宽利用率的影响,提出了一种简单灵活、普遍适用于多跳传输场景的传输机制。

英文摘要:

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.
