Embodiment 1
[0037] A reliable communication method using UDP protocol to optimize wireless network load congestion, comprising the following steps:
[0038] Step 1. After the terminal is powered on and dials up successfully, after obtaining the intranet IP assigned by the operator, it sends the first frame (first_frame) to the server. The server records the corresponding relationship between the terminal ID, IP and port, and replies to the terminal (first_frame_ack). If the terminal does not receive the reply frame, it resends the first frame at N time intervals until the reply frame is received.
[0039] Step 2, the terminal receives the first_frame_ack replied by the server, records that the connection with the server is successful, the frame number is cleared, and the actual service number can be sent, starting from 0.
[0040] Step 3, the terminal sends data according to the real-time data volume, and sends data in two windows at most, and this method realizes 32 consecutive frames. ...

The invention discloses a reliable communication method for optimizing wireless network load congestion by using a UDP. The reliable communication method comprises the following steps: step 1, a terminal is powered on and dials, obtains an IP (Internet Protocol) and sends a first frame to a server side, and the server side records and replies to the terminal; step 2, the terminal receives the reply and records connection success; step 3, the terminal sends data; step 4, the server side records the frame number received by each terminal; step 5, after receiving the retransmission request frame, the terminal retransmits the data frame corresponding to the frame number; step 6, after receiving all data of one window, the server side sends a window acknowledgement frame to the terminal; and step 7, after receiving the window confirmation frame, the terminal replies a window confirmation reply frame to the server side, adjusts the serial number of the data frame, and sends the data of the next window. According to the method provided by the invention, the load congestion of the wireless network can be improved and optimized, the reliability of data transmission is ensured, the communication parameters are adjusted according to specific applications, the communication performance is improved, and the consumption of server resources is reduced.
Description
technical field [0001] The present invention relates to a development device and method for communicating with a remote server through a wireless network transmission terminal using a 2G / 3G / 4G network for the field of Internet of Things communication, and specifically relates to a reliable method for optimizing wireless network load congestion using the UDP protocol communication method. Background technique [0002] With the improvement of wireless network communication rate, especially the arrival of the 5G era, the Internet of Things industry is developing faster and faster, and the popularity of big data, along with the data volume and reliability of data transmitted through wireless networks are also increasingly demanding. [0003] The traditional network transport layer reliable control protocol TCP is designed for wired network, and controls the network congestion with the sender as the center. The TCP data sender assumes that packet loss is caused by network conges...
