Abstract

The invention discloses a wireless sensor network data collection method based on a multi-mobile collection vehicle cooperation mechanism, which comprises the following steps: S1, an initial path construction stage: a given region is divided into sub-regions, each region is divided into a plurality of grids, a path is constructed to pass through each grid in each sub-region, and one mobile collection vehicle is distributed in each sub-region to collect data. And S2, a path adjustment stage: on the basis of the initial path, each grid is further refined into smaller grids, the number of sensor nodes in each grid is calculated, the path is adjusted to the small grid with the most sensor nodes, and the paths in the grids are connected to form an adjusted path. And S3, a cooperation stage: the mobile collection vehicle in each sub-region calculates the number of sensors and the path length in the respective sub-region, and then considers whether to help the neighbor sub-region, so that the delay of data collection can be reduced, and the life cycle of the whole network can be prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless sensor network data collection method based on the cooperation mechanism of multiple mobile data collection vehicles. Background technique [0002] Wireless sensor networks are widely used in various fields such as smart home, fire monitoring, health care, environmental monitoring, intelligent transportation, etc. Wireless sensor networks are composed of a large number of sensor nodes, each sensor node is powered by a battery, and the energy of the battery is Limited, in order to save energy, many scholars have adopted various methods and measures to reduce the energy consumption of wireless sensor nodes and improve the life cycle of sensor networks, such as charging, deployment coverage and data collection, among which the wireless sensor network (WSN) In data collection, many literatures study the deployment of a large number of static sensor nodes i...
