Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] refer to Figure 1 ~ Figure 3 , the application provides a non-cooperative game-based underwater mobile wireless sensor network power control method, which includes the following steps:

[0033] 1) Identify the target node that needs to be optimized: establish a node mobility limited model and an end-to-end delay model, and provide a suitable simulation environment.

[0034] The node movement restriction model described is as follows figure 2 As shown, this application assumes that the flow field effect of the limited range of motion area where the target node is located is the same, that is, the water velocity vector in this range is the same; The relationship between offset angle α and water flow momentum and water flow buoyancy can be expressed as α=arctan(F / f), where F is the water flow impulse force on the node, f is the water flow buoyancy on the node, ...

Abstract

The invention discloses an underwater mobile wireless sensor network power control method based on non-cooperative game theory, comprising the steps of determining a target node to be optimized; establishing an underwater mobile wireless sensor network model oriented to an underwater complex environment, including a node mobility limited model and an end-to-end delay model; according to the established underwater mobile wireless sensor network model, establishing a non-cooperative game model and a utility function; subjecting the established utility function of step 2 to Nash equilibrium analysis to obtain whether Nash equilibrium of the utility function is present or not, if yes, executing step 4, and if not executing step 2; judging whether the Nash equilibrium is unique or not, if yes, executing step 5, and if not executing step 2; solving the Nash equilibrium of step 3 to obtain a Nash equilibrium point. The single-hop end-to-end delay is reduced, and fluctuation amplitude of average power due to water flow is partly reduced.

Description

technical field [0001] The invention relates to a wireless sensor network power control method, in particular to a non-cooperative game-based underwater mobile wireless sensor network power control method. Background technique [0002] Underwater Mobile Wireless Sensor Network (UMWSN) is a wireless network formed by self-organization of a large number of multifunctional micro underwater sensor nodes with acoustic communication links. Generally, underwater sensor nodes can be deployed at different depths in the monitoring water area to form a three-dimensional network, and collaboratively monitor, sense and collect data of the measured object in the underwater environment in real time. Different from terrestrial wireless sensor network (Terrestrial Wireless Sensor Network, TWSN), the underwater environment is special and complex, and the design of power control methods and related algorithms of underwater mobile wireless sensor network often presents great challenges. Genera...
