Wireless network signal monitoring based on LAN packet capture and protocol analysis on grid programming

Abstract

As a kind of network technology with super wide coverage and obvious transmission rate advantage, wireless network has become the most widely used network technology in people’s daily life. However, when information is transmitted and exchanged in wireless networks, information blocking often occurs, which restrains the transmission rate. Therefore, the signal monitoring technology in wireless network is of great practical significance. This paper will focus on the breakthrough of wireless WLAN packet capture and protocol analysis technology in computer communication technology, and use the grid programming method to analyze the implementation process of the whole system function module. Based on this technology, a wireless network detection system is developed in VC + + 7 environment, and the algorithm flow chart is given. Finally, the system designed in this paper will be tested on Linux platform. The experimental results show that the wireless network signal monitoring technology proposed in this paper can monitor the operation of wireless network in real time. The corresponding detection accuracy error is controlled at about 1%, and the corresponding detection accuracy can reach about 60% in different signal background.
