Background
The hidden node problem occurs in the Manet and WLAN-infrastructure networks. If node A and Node B no longer transmit the power range of the other party, collision is triggered when a and B initiate communication with AP (or node C) at the same time. the more hidden nodes, the higher the probability of collision, and the lower the throughput.
Solution
Increase the node transmission power and extend the transmission range
Before starting data stream communication, int
Objective:In Linux, when a GPIO is configured as a serial port or other function, it is no longer possible to export the Gpio (echo xx >/sys/class/gpio/export) in the file system, which is not allowed because your PIN is already in use as a function of other functions.when configuring the Linux kernel, make menuconfig configures the serial port Uart2 as a case with RTS pins. Then make compile the kernel, the results run to the board, in the file syste
Frame synchronization technology is a kind of synchronization technology used in early RTS games, this article is to introduce the implementation of the frame synchronization in the Rtx game, frame synchronization is a front-end data synchronization method, generally applied to the real-time requirements of the network game, want to learn more frame synchronization knowledge, continue to look down.A BackgroundFrame synchronization technology is a kind
RTS (Require tosend, send request) is an output signal that indicates that the device is ready to receive data, the low level is active, and the low level indicates that the device can receive data. The CTS (Clear tosend, send allow) is an input signal that determines whether data can be sent to the other, low-level, and low-level instructions that the device can send data to each other. Here someone will translate CTS to send permission, I feel reall
