Problems solved by technology
When the smartphone is not rooted in the actual application, it is difficult for the terminal node to obtain the SAP access password randomly generated by the system
[0011] 22) In the topological connection, the IP addresses of the cluster head nodes are the same, resulting in only one-way data transmission. Therefore, it is not applicable in self-organizing networks that require two-way interactive functions.
Since the mobile phone needs to be rooted, it also limits the application of this network topology expansion method in ordinary smart phones

The present invention relates to the field of ad hoc networks, in particular to a method and device for establishing an ad hoc network for intelligent terminal WiFi. The present invention uses WiFi wireless local area network (WiFi WLAN) to establish each cluster, and the cluster head of each cluster acts as an access point (AP, Access Point); the branch and leaf nodes of each cluster use WiFi Direct to perform peer-to-peer (P2P, Peer to Peer ) connection, connecting multiple clusters into an arbitrarily extended multi-hop self-organizing network. At least one of the leaf nodes connected with other clusters to form an ad hoc network is an end node (STA, Station). The leaf nodes are STA end nodes or Soft Access Points (SAP, Soft Access Point), wherein the cluster head AP of each cluster establishes a cluster with any STA node or any SAP node. The connection between STA and SAP is used between clusters to realize the multi-hop network topology expansion of WiFi direct on the basis of WiFi WLAN.
Description
technical field [0001] The present invention relates to the field of ad hoc networks, in particular to a method and device for establishing an ad hoc network for intelligent terminal WiFi. Background technique [0002] At present, ordinary smart phones have been widely used, but the communication between mobile phones needs to be realized through the construction of base stations. At the same time, the related software applications of mobile phones need the support of the background service system. When 3G / 4G communication base stations are unavailable (remote mountainous areas, disaster-stricken environments, or major mission support), the communication capabilities of mobile phones will be limited. [0003] Ordinary smart phones have 3G / 4G mobile communication, Bluetooth communication and WiFi communication capabilities. Among them, 3G / 4G mobile communication depends on infrastructure and cannot be used as a connection method for mobile ad hoc networks. Bluetooth is a sh...
