Problems solved by technology

[0005] In 2011, Y. Shi proposed in the document On renewable sensor networks with wireless energy transfer.Proc.of INFOCOM,IEEE,2011 that in WSNs, a charging car is deployed to realize sensor energy by periodically visiting each sensor in the network. Complementary with fixed time slots and restricted use
[0006] For the research on the related charging method of the wireless sensor network with multiple charging cars, it mainly involves two aspects: one is the selection of the shortest path to minimize the total cost, and the other is the itinerary arrangement of multiple charging cars

Abstract

A wireless sensor network charging method with multiple charging nodes, comprising the following steps: (1) establishing a WSNs model: (2) dividing the domain range of charging cars; (3) charging each charging car: (a) initializing: , for The total number of alarm nodes received is the number of the alarm node; (b) receive the alarm signal, update the value, generate the shortest charging path, and calculate the energy discrimination vector; (c) if the vector element appears, press the corresponding Perform the charging task on the shortest charging path, otherwise return to continue updating the value; (d) execute the charging task; (e) judge whether the charging car needs to return to the parking lot to replenish energy, if necessary, return the charging car to the parking lot to replenish energy, otherwise, return to continue Update values ​​and vector elements. The invention can adaptively change the charging strategy according to the energy change of the sensor; each charging trolley is independent of each other, simple and reliable.

Description

technical field [0001] The invention relates to the field of wireless sensor network energy transmission, in particular to a wireless sensor network charging method with multiple charging nodes. Background technique [0002] The development of wireless energy transmission technology based on magnetic resonance and magnetic coupling, as well as breakthroughs in the research of ultra-fast charging battery materials in recent years, have enabled the deployment of mobile charging nodes (also known as charging cars) in wireless sensor networks The research on sensor energy supplement has attracted much attention. [0003] Wireless sensor networks are mostly used in the field of monitoring. Hundreds of sensors deployed in the network are used to collect data and transmit the data to the base station through its own communication module directly or through multiple hops, and the base station summarizes the information and transmits it to the monitoring personnel. , to achieve the ...
