Abstract

The invention discloses a multi-factor balanced overlapping non-uniform clustering WSN balanced data transmission method. After nodes in a monitoring area are clustered by adopting an overlapped non-uniform clustering method, cluster head nodes are selected by supervision and comprehensive consideration of three indexes of relative density, relative residual energy and heart rate of the nodes in the cluster, so that the network energy consumption can be better balanced; during inter-cluster data transmission, the transfer nodes in the overlapping area are combined with the cluster head nodes to jointly execute a transmission task of monitoring data, the problem that energy consumption of the cluster head nodes is too high due to the fact that data is transmitted only through the cluster head nodes is solved, and the service life of the network is further prolonged. In addition, the invention further provides a multi-factor balanced overlapping non-uniform clustering WSN balanced data transmission device and equipment and a readable storage medium, and the technical effects of the multi-factor balanced overlapping non-uniform clustering WSN balanced data transmission device and equipment correspond to the technical effects of the method.

Description

technical field [0001] The present application relates to the technical field of wireless monitoring data transmission, in particular to a multi-factor balanced overlapping non-uniform clustering WSN balanced data transmission method, device, equipment and readable storage medium. Background technique [0002] Wireless sensor network (Wireless sensor network, WSN) is composed of sensor nodes and base stations, and transmits data through self-organization. Because WSN has many advantages such as low power consumption, low cost, remote control and wireless transmission, it is more and more widely used in the fields of environmental monitoring, intelligent transportation, mine monitoring and scientific research. [0003] Due to the wireless communication characteristics of sensor nodes, all energy consumption of sensor nodes is powered by batteries, and the energy cannot be replenished. Therefore, how to balance the energy consumption of sensor nodes during data transmission, ...
