The scheme has high quality of secrecy and lowchannel transmission amount.
该方案保密性强，信道传输量低。
2
In virtual ground mode, the high channel will source and the lowchannel will sink current.
在虚拟接地模式中，高通道将提供电流，低通道将吸收电流。
3
To solve lowchannel utilization problem caused by long propagation delay in wireless networks, a fast reservation on-demand transmission (FRODT) medium access control (MAC) protocol is proposed.
