Energy Trading Method in Wireless Rechargeable Sensor Networks

Abstract

The invention discloses an energy trading strategy in a wireless rechargeable sensor network, which comprehensively considers the energy acquisition, energy consumption and remaining energy factors of the network nodes, and efficiently determines the sleep activation state of the nodes, thereby reducing the energy consumption of the network and extending the network life cycle. Each charging point obtains renewable energy and transmits it to the sensor node that requests the energy. Each sensor node will choose to enter the active or sleep state according to the actual energy acquisition and usage. The active node collects and uploads data to the base station. Charging nodes are considered buyers and sensor nodes are considered buyers. As a buyer, wireless sensor nodes hope to maximize their benefits, that is, they can consume less time in the process of wireless transmission and energy collection, and use their own energy and collected energy as efficiently as possible.

Description

technical field [0001] The invention relates to an energy transaction strategy in a wireless rechargeable sensor network, and belongs to the technical field of sleep scheduling energy transmission in a wireless sensor network. Background technique [0002] Wireless sensor networks (Wireless Sensor Networks, WSNs), due to its high degree of interdisciplinary and broad application prospects, has attracted great attention from academia and industry all over the world. [0003] At present, wireless sensor networks are widely used in many fields to process sensitive information. The application scenarios include military, industrial, family, medical, marine and other environmental monitoring and many other fields. The energy, processing power, and communication capabilities of WSNs nodes are very limited, and they are easy to die due to energy exhaustion. This requires WSNs to reduce the energy consumption of nodes as much as possible and improve the life cycle of the network und...
