Embodiment Construction

[0043] The present invention will be further described below in conjunction with drawings and embodiments.

[0044] like figure 1 As shown, the embodiment of the present invention is a collaborative underwater acoustic detection network in a circular sea area. The method for optimizing power distribution of nodes in the underwater acoustic cooperative detection network comprises the following steps:

[0045] 1) The network is initialized, and there are 12 underwater fixed source nodes (indicated by circles) distributed underwater in a shallow sea area, and the sea area is divided into 6 areas: N0, N1, N2, N3, N4, and N5 , there are 3 underwater fixed source nodes in each area, and a deep submersible or a mobile communication node is placed underwater as a relay node (the rhombus represents the relay node, and it moves in a circle around the center of the sea area) , to assist ships or base stations on the sea to communicate with the source node of the submarine underwater ac...

Abstract

The invention provides a method for optimizing the power allocation of a practical underwater acoustic cooperative detection network node, and relates to underwater communication. A mobile bathyscaphor a communication node is used as a relay node to increase the effective communication distance between an underwater fixed source node and a water surface destination node and improve the reliability of underwater acoustic cooperative communication, and the position of the relay node in the water is moved to control the signal transmitting power of the underwater fixed source nodes, so that theenergy consumption of the underwater fixed source nodes is more balanced. In addition, by adoption of the method for optimizing the power allocation of the practical underwater acoustic cooperative detection network node, when the system power is optimized, the overall system outage probability can be reduced. The power supply of the underwater movable relay node and the water surface destinationnode is relatively sufficient, and the power control is not considered for the moment.

Description

technical field [0001] The invention relates to underwater communication, in particular to a method for optimizing node power allocation in a practical underwater acoustic cooperative detection network. Background technique [0002] In recent years, with the development of marine environment monitoring, marine-related data collection, marine disaster forecasting, navigation assistance and other marine industries and marine engineering operations, people's demand for underwater communication technology is increasing. [0003] The environmental conditions of underwater communication are very harsh. As one of the most complex wireless communication channels currently recognized, the relevant parameters of the underwater acoustic channel have the characteristics of random time-space frequency variation; at the same time, the underwater noise interference is strong, and the transmission bandwidth is limited. In addition, the propagation of sound waves in water also has a strong m...
