Problems solved by technology

[0005] But so far, the main application mode of Wi-Fi Direct is used for point-to-point file direct transmission, and broadcasting cannot be realized, that is, one person in the same area transmits messages to everyone at the same time
This limits the application of Wi-Fi Direct

Embodiment Construction

[0018] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0019] The method for establishing the maximum coverage broadcast tree based on the Android WI-FI DIRECT mode includes the following steps:

[0020]Step 1: A node i that wants to join the broadcast group first enters the state of listening and searching periodically according to the WI-FI P2P technical specification. In the listening state, listen to the probe request (probe request) message of other nodes. In the search state, initiate a probe request (probe request) message on the wifi channel, ...

Abstract

The invention discloses an Android WI-FI (Wireless Fidelity) direct mode based maximum coverage broadcast tree establishment method which is applied to the implementation of the information multi-hop sharing among a plurality of intelligent terminals with WI-FI modules, wherein the above Android 4.0 version operation is performed on the plurality of intelligent terminals. A broadcast tree is established in a WI-FI direct mode supported by the above Android 4.0 version without relying on the 2G (Second Generation) / 3G (Third Generation) / 4G (Fourth Generation) mobile base stations and WI-FI hotspots, the multi-hop broadcasting can be implemented among multiple users without the root, and accordingly the application range of the WI-FI direct is extended. Neighbors of core forwarding nodes of the established broadcast tree are more in participation members and accordingly the wide coverage of the broadcast tree is ensured, the depth of the broadcast tree is small, and accordingly the end-to-end broadcast delay can be maintained to be a low value.

Description

technical field [0001] The invention relates to a Wi-Fi Direct mode based on an Andriod operating system, which is applicable to a method for establishing a maximum-coverage broadcast tree for mobile phones running an operating system above Andriod 4.0, and belongs to the technical field of wireless communication. Background technique [0002] In recent years, smartphones have gained widespread popularity. There are mainly two mainstream operating systems on smart phones: Android operating system and IOS operating system. Among them, the IOS operating system is developed by Apple and is mainly used for Iphone series mobile phones, while the Android operating system is developed by Google. The running operating system covers Samsung and most domestic mobile phones such as Huawei and ZTE, as well as a large number of smart home systems such as TV etc. Most of these mobile phones are integrated with Wi-Fi chipsets, which can realize wireless data transmission, and various wir...
