Problems solved by technology

The existing data transmission methods have the following deficiencies: 1. In order to obtain a faster transmission rate, too many underwater nodes compete for the channel of wireless optical communication, resulting in an overcrowded channel, which reduces the transmission rate and increases the delay. ;2. In order to be able to use wireless light for data transmission, underwater nodes continue to delay the time of data transmission, resulting in a decline in service quality and a reduction in the amount of data that underwater network users are willing to transmit

Embodiment 1

[0046] Such as Figure 4 and Figure 5 Shown is to evaluate the performance of the communication link selection method for underwater data transmission based on the auction game theory proposed by the present invention, and show the performance of the transmitted data and the average service delay. The modeling experiment was carried out in an area of ​​2.0km*2.0km off the coast of Dalian. The SDNC is placed in the center of the simulation test area, and the BTS is randomly deployed in the test area. Each BTS has a certain coverage area, and their coverage areas may overlap, but the overlapping area we default here will not have a great impact on data transmission. We assume that within the area of ​​wireless optical transmission, the UNU can immediately transmit data through wireless light without spending time to obtain access permission. In the simulation experiment, we set D a =1Mb / $, W=2KHz, [δ min ,δ max ]=[0,2], so the transmission rate of underwater acoustic comm...

Abstract

The invention discloses an underwater data transmission communication link selection method based on an auction game theory. Data auction is carried out on underwater network users having optical transmission underwater and being within the underwater acoustic transmission coverage area, so that the underwater network users winning the data auction carry out data transmission through wireless light transmission, and the underwater network users not winning the data auction carry out data transmission through acoustic transmission or wait for the next auction. According to the method, the usersoccupying optical channels underwater are reduced and the problems of descending of the transmission rate and large time delay, which are caused by channel congestion, are effectively solved.

Description

technical field [0001] The invention relates to the field of underwater communication, in particular to a method for selecting communication links for underwater data transmission based on auction game theory. Background technique [0002] In the underwater communication process, underwater network users only use underwater acoustics / wireless light for data transmission; when underwater network nodes are in the coverage area that wireless light can transmit, they all use wireless light for data transmission . The underwater network nodes outside the wireless optical coverage area use underwater acoustics for data transmission. When the underwater network node is not in the coverage area of ​​wireless optical transmission, the data transmission does not proceed immediately, but continues to wait for the opportunity of wireless optical transmission until it enters the coverage area of ​​wireless optical transmission. The existing data transmission methods have the following ...
