Summary Wireless Sensor Networks (WSNs) have been widely considered as one of the most important technologies with unique characteristics designed for various applications. However, one of the major problems in WSNs is a limited lifetime. The creation of an energy hole near the sink has been a chief concern for researchers working to mitigate the lifetime problem. The data transmission in a multi‐hop network, as used for military purposes, follows a many‐to‐one pattern resulting in a heavier traffic load for nodes near to sink. Hence, these nodes deplete energy very soon resulting in a vacuum of energy and breakage of the network. This article aims to mitigate the energy hole problem (EHP) by implementing a corona‐based model in a clustered network. Here the cluster head selection is regularized by preferring the outer corona nodes over the inner ones. As a result, the energy balances evenly in the network with fewer loads to the nodes nearer to the sink. The distance between the sending node and the sink is evaluated to estimate the required energy for transmission. Only when a node has energy more than the required value, it is allowed to transmit, or else it turns off the radio to save energy. The proposed model is implemented in both homogeneous and heterogeneous networks and better network performance is observed.
