Abstract It is undeniable that there are a large number of redundant nodes in a wireless sensor network. These redundant nodes cause a colossal waste of resources and seriously threaten the life of the sensor network. In this paper. we provide a sensor nodes optimization selection algorithm based on a graph for a large-scale wireless sensor network. https://www.royaltyfurnitureandappliancers.shop/product-category/memory-foam-mattresses/
