Abstract

The invention discloses a network path planning method which is applied to an ultraviolet light wireless network. The method comprises the steps that a broadcast message for acquiring immediate familymember information of a node in the network is sent, wherein the immediate family member information comprises the node and node identifier information of other nodes which have a line connection relation with the node; a returned message, containing the immediate family member information of the node, of any one node is received; a network topology is generated according to the immediate familymember information of each node; and a network path needing least hops for reaching a target node is planned according to the network topology. The invention further provides node equipment and a computer storage medium. According to the network path planning method, the node equipment and the computer storage medium, the path planning problem that information exchange between two nodes which havea relatively long distance in the ultraviolet light network needs to be achieved through multiple relay nodes can be solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a network path planning method and node equipment. Background technique [0002] Ultraviolet light communication is a new type of communication method that uses atmospheric scattering for information transmission. It is divided into two types of communication methods: line-of-sight and non-line-of-sight. The line-of-sight requires that the transmitting and receiving ends be aligned, and there must be no obstacles between the two. In the non-line-of-sight mode, ultraviolet light reaches the receiving end through the scattering of atmospheric molecules and particles, and the receiving end receives a certain number of ultraviolet photons to realize non-line-of-sight communication. [0003] Non-line-of-sight ultraviolet communication has the advantages of strong anti-interference ability, good confidentiality, and all-round communication. It can be used as a n...
