Wireless sensor network (WSN) nodes are devices with limited power. and rational utilization of node energy and prolonging the network lifetime are the main objectives of the WSN’s routing protocol. However. irrational considerations of heterogeneity of node energy will lead to an energy imbalance between nodes in heterogeneous WSNs (HWSNs). https://allfixelectricales.shop/product-category/cartridge-spacer-weight/
