Data fusion alliance game method and system for wireless sensor network

Abstract

The invention discloses a data fusion alliance game method and a data fusion alliance game system for a wireless sensor network. The method comprises the following steps: building an alliance game model based on the wireless sensor network, taking a Shapeland value as a solution of alliance income distribution, and determining a relay node according to the size of the Shapeland value; taking the unmanned aerial vehicle as an aggregation node in the wireless sensor network to collect data, and determining a flight path and a flight direction of the unmanned aerial vehicle; and the unmanned aerial vehicle performs preliminary data fusion on the collected data, and removes repeated parts in the collected data. According to the invention, the unmanned aerial vehicle is used as a mobile aggregation node in the wireless sensor network; a proper sensor data transmission path is selected according to the Shapley value, so that the energy consumption of the sensor is more uniform, more reasonable and more efficient, the life cycle and the working efficiency of the wireless sensor network are improved, the data storage amount of the unmanned aerial vehicle is reduced by adopting data fusion,and the working time of the unmanned aerial vehicle is prolonged.

[0002] Wireless Sensor Networks (WSN) is a new generation of integrated technology that is developing rapidly. The sensors in the existing wireless sensor networks usually use batteries as energy sources. The current battery capacity is limited, and with the deployment of sensors in remote locations or tasks It is particularly difficult to charge or replace the battery, which is not enough to ensure the long-term high-power use of the sensor. Once the battery energy is exhausted, data can no longer be collected; The role played in the data transmission process is different, resulting in uneven energy consumption, causing some nodes to exhaust energy prematurely, affecting the function of the wireless sensor network;

[0003] On the other hand, due to the limitation of the communication module and the power module, the data transmission radius of the sensor cannot perform long-distance data transmission, and can only be transmitted within a limited distance. The relay node is not changed during the process, resulting in excessive energy consumption of the relay node and shortening the life cycle of the wireless sensor network; and because the deployment location is remote or the task is special, multiple fixed base stations need to be deployed, the cost is high, and the fixed The base station cannot balance the energy consumption among the sensors, and the energy consumed by the unit data transmission of the sensor far away from the base station is more than that of the sensor close to the base station, so the life cycle of the wireless sensor network ends too quickly
