Abstract

The invention provides a WIFI probe realization method and device based on Openwrt. The method comprises the steps that each AP starts application service and receives probe data; the AP application service establishes a multicast group and the AP application service joins in the multicast group as a multicast group member; the AP application service receives a netlink multicast message of a kernel mode in a blocking mode; message validity judgment is carried out on the netlink multicast message of the kernel mode, so the netlink multicast message of the kernel mode is further processed. According to the method and the device, duplicated data is filtered, CPU loads of the APs are reduced, a netlink multicast mechanism is employed, multi-application service subscription is supported, multiple users are supported, moreover, the repeated data sending is reduced, and bandwidth resources are saved.

Description

technical field [0001] The invention belongs to the technical field of mobile Internet, and in particular, the invention relates to a method and equipment for implementing a WIFI probe based on Openwrt. Background technique [0002] With the increasing development of wireless network technology, traditional wired access is increasingly limited to the access of IT operation enterprises and fixed facilities, while in daily life, people mainly use wireless access. It can be said that the wireless network has occupied a very important position in people's daily life and work. Today, people can no longer live without the wireless network, and people's life is increasingly dependent on the wireless network. Due to the wide application of big data, the demand for basic data is increasing day by day. WIFI probe data is one of the basic data, which can be applied to many fields, such as passenger flow statistics, advertising, attendance, public safety and other fields. [0003] The...
