A Node Energy Saving Method Applicable to Linear Wireless Sensor Networks

Abstract

The invention discloses a node energy-saving method applicable to a linear wireless sensor network, comprising steps: 1. Constructing a linear wireless sensor network; 2. Clustering a plurality of wireless sensor nodes in the wireless sensor network; 3. Clustering within a cluster Head node election; 4. The cluster head node transmits data to the base station in a multi-hop transmission mode. The invention clusters a plurality of wireless sensor nodes in a linear wireless sensor network formed in a long straight roadway, selects a cluster head node according to the position and energy of the wireless sensor nodes in the cluster, and the cluster head node transfers the data in a multi-hop transmission mode Transmission to the base station, so that the energy consumption of the wireless sensor nodes is balanced, the energy consumption is reasonable, and the selected cluster head nodes are avoided from being too concentrated or too scattered, and the communication between the nodes in the cluster and the cluster head nodes or between the cluster head nodes and the base station nodes The transmission energy consumption is too large, which enhances the life cycle of the wireless sensor network and avoids premature paralysis of the wireless sensor network, resulting in waste of node energy.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network energy saving, and in particular relates to a node energy saving method suitable for linear wireless sensor networks. Background technique [0002] In order to solve the problem of environmental pollution caused by surface subsidence and tailings stockpiling on the surface due to mineral mining, most schemes use filling pipes to make various filling materials such as tailings, cement and gravel into slurry or paste. The goaf is filled. However, as the working time continues to increase, the filling slurry with different concentrations will undergo a hydration reaction in the pipeline, causing the filling pipeline to agglomerate or even block the pipe. Once the pipe is blocked or a pipe burst accident occurs, it will cause serious environmental pollution and economic loss. Existing mine filling pipelines use ERT sensors and wireless sensor network technology to perform real-time d...

Problems solved by technology

The LEACH protocol guarantees that each node has the opportunity to become a cluster head node in the cluster head node election, but it does not consider the position of the node and the current energy of the node during the cluster head node election process, and the selected cluster head node may appear Too concentrated or too dispersed, the transmission energy consumption between the nodes in the cluster and the cluster head node or between the cluster head node and the base station node is too large, which will cause a waste of node energy and lead to a short life cycle of the entire network
