Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035]The present invention is a wireless sensor network clustering routing method based on inter-node correlation, which divides the wireless sensor network into clusters with balanced energy consumption according to the position correlation, numerical similarity, and synergy between nodes, and makes node communication low energy consumption .

[0036] The first step is to calculate the minimum energy consumption for any node to communicate with all neighbor nodes

[0037] Any node A has multiple communication energy levels. Node A communicates with neighboring nodes of different distances by changing the communication energy level, that is, the node close to node A chooses low communication energy level, and the node far away from node A chooses high communication energy level. energy level. The perceived data values ​​of node A and neighbor nodes are sim...

Abstract

The invention discloses a wireless sensor network clustering routing method based on correlation among nodes. Position correlation and numerical value correlation among the nodes are taken as the basis of communication energy consumption of the nodes, and cooperativity among the nodes is taken as the basis of selecting a cluster head node by the nodes. The method comprises the following steps of:firstly, calculating lowest energy consumption for communicating any node with a neighboring node; secondly, generating a temporary cluster head node according to the residual energy probability of the node; thirdly, selecting the temporary cluster head node as a final cluster head node; fourthly, selecting the node with the lowest energy consumption as the final cluster head node; and finally, selecting a neighboring final cluster head node with the lowest energy consumption as the cluster head node in which a non-cluster head node joins by using the non-cluster head node. According to the method, a network in which the cluster head nodes are uniformly distributed can be formed, two or more cluster head nodes cannot exist in a cluster range, the number of member nodes in each cluster is similar, the energy consumption of the cluster head nodes is similar, and the member nodes in the cluster have low communication energy consumption, so that a wireless sensor network with balanced andlow energy consumption and effective energy is realized.

Description

technical field [0001] The invention relates to the cluster head selection and cluster organization method of the hierarchical cluster routing of the wireless sensor network, and more particularly refers to a cluster routing method of the wireless sensor network based on inter-node correlation. The cluster routing method realizes energy efficient wireless sensor network. Background technique [0002] The wireless sensor network is composed of a large number of cheap micro sensor nodes deployed in the monitoring area, and its purpose is to cooperatively perceive, collect and process the information of the perceived objects in the network coverage area, and send it to the observer. Wireless sensor networks are widely used in military, environmental monitoring and forecasting, health care, smart home, building status monitoring, complex machinery monitoring, urban traffic, space exploration, large workshop and warehouse management, and security monitoring of airports and large ...
