Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0041] In the ultraviolet optical communication network system, each node is within the effective communication range of other nodes; any node sends data, and other nodes can receive it, which can be regarded as broadcast data; the ultraviolet optical communication channel is set as a single optical wavelength channel, that is, Multiple network nodes share a single optical wavelength channel; communication between nodes is based on competition for access channel resources, and the corresponding multi-node contention access conflict problem needs to be solved.

Abstract

The present invention discloses a dynamic priority UV communication network access system and its method in the field of wireless optical communication technology and networking technology. It aims to solve the competition access of multiple ultraviolet light communication terminal nodes in existing technologies.Conflict loss and technical problems lacking fairness.It includes light -based superposition and proposes a light bus in the UV light communication network channel. Based on the state of the optical total line, communication between nodes is connected to UV communication network channels based on dynamic priority competition.The present invention can adjust the channel utilization rate, simplify the design and achieve complexity by using dynamic priority adjustments, and has a high channel access to fairness.

Description

technical field [0001] The invention relates to an ultraviolet optical communication network access system with dynamic priority and a method thereof, belonging to the field of wireless optical communication technology and networking technology. Background technique [0002] In recent years, people have tried to design new networking methods and access mechanisms based on the relevant protocols of radio communication ad hoc networks, and according to the physical characteristics and technical characteristics of ultraviolet light communication. in: [0003] The traditional access systems and methods based on time division multiplexing have the disadvantages of low bandwidth utilization, low network throughput and large network delay, and are not suitable for occasions where there are many network nodes; while the random access protocol based on asynchronous grouping, due to the introduction of Therefore, the complexity of the protocol is greatly increased, and the performanc...
