Wireless sensor network routing method based on uniform clustering and data aggregation

Abstract

The invention discloses a wireless sensor network routing method based on uniform clustering and data aggregation. The implementation method comprises the following steps: (1) according to the minimum of network energy consumption, determining the minimum transmission distance, the number of optimal cluster heads and the minimum distance of the cluster heads in the network; (2) selecting nodes with larger energy and uniform distribution to be used as cluster heads in the network by using the number of the optimal cluster heads and the minimum distance of the cluster heads; (3) using all cluster heads nodes and SINK nodes to form a minimum tree, which uses the SINK as a root, to be used as a inter-cluster routing according to the minimum transmission distance; and (4) members of the cluster nodes sending data to the cluster head nodes, the cluster head nodes aggregating the received data and perceptible data thereof into a data packet, then sending the data to a gateway SINK node along the established inter-cluster routing. Compared with the prior art, the wireless sensor network routing method based on uniformly clustering and data aggregation has the advantages of high scalability, long network life cycle and low delay, and can be used to achieve data collection and transmission of the wireless sensor network with different scale.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to uniform clustering and data aggregation methods, in particular to a wireless sensor network routing method based on uniform clustering and data aggregation, which can be used to improve the life cycle and network delay of the wireless sensor network. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and wireless sensor networks (WSNs) have greatly promoted the Internet of Things, and it plays an important role in the perception layer. A wireless sensor network refers to a network formed by cooperation and communication between a large number of sensor nodes deployed in a detection environment. Its main function is to perceive, collect and process the information that the observer is interested in in the network coverage area, and send it to the observer. Wireless sensor networks have broad application p...

AI Technical Summary

Problems solved by technology

[0005] 1) During the operation of the entire network, the total energy consumption of the network increases due to too many cluster heads, and too few cluster heads lead to excessive energy consumption of the cluster heads, which eventually leads to premature failure of network nodes. More importantly, these methods Poor scalability, not adaptable to changes in network scale

[0006] 2) The network does not consider the delay of data transmission. When the number of hops between clusters is too large, the delay of data transmission between clusters increases; The delay of sending data to the cluster head node also increases

[0007] These defects limit the performance of wireless sensor networks, resulting in increased energy consumption, shortened life cycle and increased network latency.
