Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] Based on the underwater acoustic communication energy consumption model and combined with cooperative communication technology, the present invention can quickly find the path with the least energy consumption in the underwater acoustic multi-hop cooperative communication network, including the following steps:

[0041] 1) Consider a small to medium network topology, such as figure 1 , select node 1 as the source node S, and node 18 as the destination node D;

[0042] 2) Calculate the distance d between each node i,j and the optimal operating frequency f between nodes opt ;

[0043] 3) Initialization parameters: set the number of ants to be searched in each round to M, the number of searches to be N rounds, and the distance threshold for successful direct transmission between two nodes to be d hop , the distance threshold for coope...

Abstract

The invention discloses a water sound multihop cooperative communication network route selection method based on an ant colony algorithm, and relates to a water sound network. Cooperative communication is introduced into the water sound multihop network, a water sound multihop cooperative communication network is formed, and an ant colony algorithm cost function suitable for the water sound multihop cooperative communication network is put forward according to a water sound communication energy consumption model for optimizing route selection; a cooperation node exists, the next hop selection space of each relay node is increased, and the success rate of route selection is increased; under the condition that the relay nodes and cooperative nodes exist, a global optimum path can be sought fast and effectively; by means of the optimal path, system overall energy consumption can be reduced, and the life cycle of the water sound communication network can be prolonged.

Description

technical field [0001] The invention relates to an underwater acoustic network, in particular to an ant colony algorithm-based routing selection method for an underwater acoustic multi-hop cooperative communication network. Background technique [0002] With the continuous development of terrestrial resources, in order to alleviate the shortage of resources, people have turned their attention to marine resources with rich reserves and great potential. In recent years, due to the gradual increase in the application requirements of underwater acoustic communication in the military and civilian fields, the research on underwater acoustic communication and its network technology has gained people's favor. [0003] Due to factors such as the narrow available bandwidth of the underwater acoustic channel, the severe attenuation of underwater acoustic signal transmission, and the limited energy supply of underwater nodes, studies have shown that compared with direct long-distance tr...
