Wireless sensor network data acquisition method based on multiple mobile factors

Abstract

The invention discloses a wireless sensor network data acquisition method based on multiple mobile factors, and aims to save energy consumed by transmission of a large amount of data, effectively use network resources, prolong the service life of a network and balance a relation between multiple hops and cache overflow. The wireless sensor network data acquisition method comprises the following steps of 1, acquiring data by forming a tree-shaped structure by network self-organization; 2, informing node state information to a base station and a direct subsequent node by a low-electric-quantity node; 3, dispatching multiple mobile factors to respective sub-trees to finish corresponding acquisition tasks by the base station, wherein when the whole network is divided into a plurality of sub-trees, the nodes in the sub-trees acquire the data and forward the data to the mobile factors through one hop when the mobile factors dispatched by the base station reach a communication radius range instead of forwarding the data according to an original tree-shaped structure; 4, designing the optimal path of the mobile factors; and 5, cooperatively finishing data acquisition of the whole network by the mobile factors.

Description

[0001] technical field [0002] The invention provides a data collection method in a wireless sensor network, which belongs to the technical field of wireless sensor networks. [0003] Background technique [0004] Wireless sensor network is a new type of self-organizing network. A large number of sensor nodes are deployed in the target area, forming a self-organizing network system through wireless communication, which can cooperatively perceive, collect and process the information sensed in the network coverage area, and transmit it to the management terminal. However, sensor nodes are usually limited in terms of energy, communication, computing and storage capabilities. Especially when nodes are deployed in harsh environments, energy limitation has become the bottleneck of wireless sensor networks, and this problem is exacerbated with the expansion of network scale. Therefore, designing an energy-efficient communication mechanism to effectively collect sensor data and ...
