RTS/CTS message switch ｡ CSMA/CA Protocol CSMA is a random competitive MAC protocol with simple algorithms and rich performance. Therefore, CSMA has been widely used in practical LAN applications, due to the inherent characteristics of wireless transmission media and the impact of mobility, MAC of a wireless LAN is different from that of a wired LAN in terms of Error Control and terminal hiding. Therefore, CSMA of a WLAN is different from that of a w

conversion before and after transmission. The default value is asciiencoding. Asciiencoding does not provide error detection. For security reasons, we recommend that you use utf8encoding, unicodeencoding, or utf32encoding and enable error detection. Asciiencoding only supports Unicode character values between U + 0000 and U + 007f. Therefore, utf8encoding, unicodeencoding, and utf32encoding can better adapt to global applications.Program. 18. dtrenable gets or sets a value. The default va

Systems (distribution System): logical components belonging to 802.11 that are responsible for forwarding frames to the destination. A distributed system is a backbone network that forwards frames between access points, so it is often referred to as a backbone (backbone network).The RTS frame itself has two purposes: to reserve the right to use the wireless link and to remain silent on other workstations that require this frame to be received. Once the RTS frame is received, the receiving end i

method. Figure 4 shows the flowchart of image file transmission on the GPRS client using the data subcontracting method. In this method, the image file is first packaged into several small data packets and written to the serial port one by one, which is sent by the GPRS module. The monitoring center server receives a packet and then returns the response frame. The GPRS module then sends the next packet. If the response frame is not returned after the timeout, resend the previous packet. This

Since it is considered as "null reference", it willStackThe previous Slot" , There is a pointer in it that does not point to any place (in other words, there is no value on the stack ). next, let's talk about the difference between string S = string. Empty and string S = NULL. Here we also want to talk about the difference between string and string. We can't see the difference between them during development in Visual Studio, because the information presented t

Port connection (the key is to connect to the modem through the serial port), issue commands, exchange data, and monitor and respond to events and errors in the serial connection. The MSComm control can also be used to create dialing programs, serial communication programs, and terminal programs with complete functions.The MSC

When learning the Spring Framework base bean package, a simple example is written, similar to the following: Package Study.spring.bean; public class Simplebean { Private String Beanname; Private Simplebean () { System.out.println ("Simplebean"); } /** */ /** * @return Returns the beanname. */ Public String Getbeanname () { return beanname; } /** */ /** * @param beanname the beanname to set. */ public void Setbeanname (String beanname) { this.

Due to the fact that wireless LAN transmission media (microwave and infrared) are not "Limited" wired, there are some new technical difficulties objectively. For this reason, the Protocol sets out some crucial technical mechanisms, for example, CSM/CA and RTS/CTS.1. CSMA/CA protocol we know that the standard protocol for a bus LAN on the MAC layer is CSMA/CD, that is, the carrier listens for Multi-Point Access/conflict detection (carriersensemultiplea
