智能自组网系统关键技术

Key Technologies of Intelligent MESH Network System

无线自组网具有无中心、多跳中继、动态路由以及抗毁性强等特点,适用于不需要事先部署但需要临时开通1个专用网络的场景。首先介绍无线自组网系统,其次指出自组网系统的发展趋势是使用简单、宽窄融合、小型化和性能增强,最后对智能自组网系统的自适应编码调制、智能选频、智能跳频、子载波动态扣除、载波带宽自适应、网络规模自适应、功率控制自适应、通信距离自适应、混合自动重传、路由自适应以及静默自适应等关键技术进行探讨。

Wireless AD hoc network has the characteristics of centerless,multi-hop relay,dynamic routing and strong invulnerability,etc.,so it is suitable for the scene where a private network needs to be temporarily opened without prior deployment.Firstly,the wireless AD hoc network system is introduced.Secondly,it is pointed out that the development trend of AD hoc network system is simple to use,wide-narrow integration,miniaturization and enhanced performance.Finally,the key technologies of intelligent AD hoc network system,such as adaptive coding modulation,intelligent frequency selection,intelligent frequency hopping,subcarrier dynamic deduction,adaptive carrier bandwidth,adaptive network scale,adaptive power control,adaptive communication distance,adaptive hybrid automatic retransmission,adaptive routing and adaptive silence are discussed.
