Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] Thermoelectric battery power supply technology has been more and more widely used in the design of wireless sensor network nodes. However, the energy collection of thermoelectric batteries is very difficult. Therefore, it is necessary to propose a system that saves energy consumption of nodes and is used to stabilize the entire sensor network. work on. Based on the thermoelectric battery technology, the present invention establishes a relatively systematic wireless sensor network transmitter power optimization allocation scheme, which has high practicability, as described below for details:

[0041] 101: Establish a wireless sensor network node model based on a thermoelectric battery;

[0042] The wireless sensor network node m...

Abstract

The invention discloses a wireless sensor network dynamic energy allocation method based on a thermoelectric cell. The method includes: building a wireless sensor network node model based on the thermoelectric cell; recording and storing power acquired by the thermoelectric cell and signal to noise ratio of wireless channels; acquiring water injection lines vi of time division slots; acquiring water injection lines of time division slots which satisfy power limitation on the time dimension, and determining allocated power of each time slot according the water injection lines. The thermoelectric cell is used to power wireless sensor network nodes, power generated by the thermoelectric cell is allocated in an optimized manner to achieve maximum throughput of information transmission. By the method, allocation of power acquired by the thermoelectric cell in the wireless sensor network nodes is achieved, and energy utilization efficiency is increased. The method is high in portability and large in application space.

Description

technical field [0001] The invention relates to the field of dynamic energy collection, in particular to a dynamic energy distribution method for a wireless sensor network based on a thermoelectric battery. Background technique [0002] With the development of science and technology, wireless sensor network technology has penetrated into all aspects of human production and life. The wireless communication network has gradually developed into the Internet of Things that can communicate between any person and any object anytime and anywhere. The scale of the network is expanding rapidly, but at the same time, the overall stability and sustainable development of the Internet of Things are becoming more and more prominent. At the same time, in order to meet the needs of human life, more and more sensors need to be placed in inaccessible or harsh environments. The harsh environment of these areas determines that people cannot use chemical batteries to power wireless sensor nodes,...
