Adaptive dynamic channel allocation method for mobile multimedia in Internet of things

Abstract

The invention discloses an adaptive dynamic allocation method for wireless channels, which is characterized in that: the method comprises the following steps that: after setting up a network, a center node monitors a wireless channel, regularly sends network heartbeat frames, and guarantees that clocks are synchronized in the network; and the center node intercepts the network, carries out analysis on the type of the data package when a network data package is received, turns to a step (3) when the network data package is a network access request, turns to a step (4) when the network data package is a multimedia communication request, turns to a step (5) when the network data package is multimedia communication data, turns to a step (6) when the network data package is a multimedia communication completion request, turns to a step (7) when the network data package is a mobile multimedia node broadcast message, and turns to a step (8) when network data package is a network access point RSSI (received signal strength indicator) upload message.

Description

[0001] The present invention relates to a method for adaptive dynamic allocation of wireless channels, in particular to an adaptive dynamic channel allocation method for mobile multimedia in the Internet of Things. Background technique [0002] The Internet of Things collects terminal device information in real time through various information sensing devices and technologies, combines with each other to form a network, and finally realizes the interconnection between things and things, things and people. As the core component of the Internet of Things, wireless sensor network (WSN) has a wide range of applications. By introducing the multimedia information perception function into WSN, more accurate environmental monitoring can be achieved and the application field of the Internet of Things can be expanded. However, since the data characteristics and transmission characteristics of multimedia data and WSN are obviously different, it is necessary to solve the data flood proces...

AI Technical Summary

Problems solved by technology

WSN faces huge challenges when processing multimedia data: when there is a large amount of data to be transmitted, it is easy to cause network congestion; data delay is large, and clock synchronization cannot be guaranteed, etc.

In addition, many multimedia nodes are portable devices. When the multimedia nodes move, the network structure will change. The current WSN does not have a good solution for the processing of mobile multimedia nodes.
