Embodiment Construction

[0038] Below in conjunction with embodiment the present invention will be further described.

[0039] The present invention (hereinafter referred to as the system) introduces a multi-channel communication method based on Bluetooth cooperation based on MANET (MobileAdhocNETworks, mobile ad hoc network). The system works under the Android mobile phone system. The system includes three modules: network management module, channel switching module, and data sending module. Each node contains its own corresponding IP address. Existing network communication protocols are used on the nodes.

[0040] Such as figure 1 As shown, after the system is started, when the application program needs to transmit data, it does not use the traditional socket (socket) for data transmission, but uses the corresponding API provided in the present invention to transmit data. Subsequently, the multi-channel transmission program takes over the sending work of the data, realizing the transparent trans...

Abstract

The invention discloses an ADHOC network multichannel communication method based on bluetooth cooperation. The method is characterized in that: in a mobile streaming media system based on MANET, a bluetooth communication protocol serves as a cooperation mechanism, and on the premise of unchanged present hardware, a double-layer ADHOC network is simultaneously established through the Bluetooth and a WIFI antenna; router information is managed independently; time domain information of a network state serves as a channel selecting strategy, and a cache strategy is used to perform dispatchment of a data package, so that a single network card device is enabled to use a plurality of non-interfering channels to transmit data, the problem of decreasing performance brought by multi-node under the current ADHOC network single channel is solved, and the transmitting performance of the network is improved. According to the invention, the universality and the expansibility are high, and the communication performance of the mobile ADHOC network can be improved effectively.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a bluetooth-based ADHOC network multi-channel communication method. Background technique [0002] With the rapid development of mobile communication technology and the rapid progress and large-scale popularization of mobile terminal technology represented by smart phones, mobile Internet has become an increasingly important part of modern social life. With the continuous development of mobile Internet applications, the information society has entered the era of mobile Internet. [0003] The core of the mobile Internet lies in wireless data communication. In the traditional 2G era, cellular networks can only support voice calls and short message services. The arrival of 3G communication makes high-performance network data transmission possible. With the popularization of 3G and 4G networks, mobile cellular networks can provide more powerful communication performance to mee...
