Problems solved by technology

The disadvantage of the TopDisc algorithm is that the overhead of repeated execution of the algorithm is large, and the remaining energy of the nodes is not considered, so the rationality of clustering is not good.

Embodiment Construction

[0024] A non-cooperative game-based underwater wireless sensor network topology control method of the present invention will be described in detail below.

[0025] The method of the present invention firstly analyzes the three behavioral characteristics of nodes based on game theory, formulates the behavioral characteristics of nodes, and formulates forwarding strategies for nodes in combination with the information of neighbor nodes and energy information of nodes, so as to reduce the energy consumption of nodes. Nodes in a wireless sensor network are usually randomly deployed in large numbers. It is difficult to replace the battery of the node, and the communication capability and energy are limited. Data information is forwarded between nodes in a multi-hop manner. Each node needs other neighbor nodes to forward data for it. . In order for neighbor nodes to help forward data for themselves, nodes must use their limited energy to serve other nodes, but forwarding data will c...

Abstract

The invention provides a topology control method of an underwater wireless sensor network based on a non-cooperative game. The method comprises the steps that based on a cooperative evolutionary theory, three behavior characteristics of nodes are analyzed first, after the behavior characteristics of the nodes are formulized, the forwarding strategy of the nodes is made combining with the energy information of the nodes, and the node with the high forwarding probability is chosen to conduct data forwarding. The topology method of the underwater wireless sensor network based on the non-cooperative game can reduce the energy cost of the nodes, balance the energy of the network nodes, prolong the life cycle of the entire network, and be suitable for the underwater wireless sensor network with limited node energy.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a non-cooperative game-based underwater wireless sensor network topology control method. Background technique [0002] The topology control of underwater sensor network is the cooperative control of the interaction between nodes, so that the local optimization adopted by the nodes can promote the evolution of the network to the global optimization on a macro level. , operations research, game theory and other multi-disciplinary related technologies. According to different division methods, topology control can be divided into node power control and hierarchical topology structure. Commonly used algorithms based on power control are: COMPOW algorithm, local average LMA (Local Mean Algorithm) algorithm based on node degree and local neighbor average LMN (Local Mean of Neighbors Algorithm) algorithm, and local minimum spanning tree LMST (Local Minimum Spanning Tree) ...
