无线多跳链路选频通信

加入无线中继节点构成多跳传输链路，可以实现较长距离的无线通信。本文在已有文献的基础上，重点研究救灾机器人和遥控终端间的选频建路协议，在链路各节点间按照选频通信的方式搭建传输链路；并在“全节点比例定时交替传输协议”基础上加入选频通信，设计选频传输协议，避免数据包间的相互碰撞。经仿真测试，设计的协议按照选频通信方式搭建了传输链路并实现了数据的无碰撞双向传输。

Wireless multi-hop link based on frequency selection communication

Multi-hop transmission link can achieve long distance wireless communication by adding wireless relay nodes. On the basis of the existing literatures, a multi-hop building route protocol between the rescue robot and the operation console is studied in emphasis,and a transmission link is established by using the technique of frequency selection communication. In order to avoid the collisions among wireless packets, a transmission protocol based on the full-time alternate node transmission protocol is designed by adding the technique of frequency selection communication. According to the simulation test, a transmission link can be established based on the designed protocols and bidirectional data transmission can be realized without collisions.
