A method for wireless network topology detection

Abstract

In the wireless network topology detection method of the present invention, its wireless network includes a processing center served by an ordinary computer, a tested network composed of several devices following the IEEE802.15. The detection node is composed of network data devices. This method captures and uploads the data packets sent by the network under test in real time through the detection nodes, and the processing center displays the topological connection relationship on the display screen by analyzing the device address information in the data packets. This method will not have any active intrusion impact on the network, and can provide testers with node topology relationships, help testers find problems, and improve test efficiency; in addition, this method can realize topology detection of deployed networks and help maintenance personnel There is a problem with the detection network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for wireless network topology detection. Background technique [0002] In recent years, a large number of products based on the IEEE802.15.4 communication protocol have been put into the market, but there are some difficult problems in the development and deployment of networks based on the IEEE802.15.4 communication protocol, the most important of which is the detection of the wireless network topology: a On the one hand, when testing this series of wireless networks, the testers are not clear about the relationship of the nodes in the topological network. When detecting, it is necessary to ensure the normal operation of its equipment and avoid interfering with the normal operation of the product and the security performance of the network. At present, there is almost no detection of the topology of the Internet of Things in China. Contents of the invention [0...
