Recent developments in wireless sensor networks (WSNs) have given rise to a number of routing protocols created especially for sensor networks where power consumption is a key consideration. Due to their battery-powered nature, Sensor Nodes (SNs) in WSNs are constrained in terms of computational capacity, transmission distance, and energy. Since these SNs cannot be recharged when placed in hostile environments where reachability is impossible, protocols for WSNs should be created with consideration for energy usage. Wireless sensor network routing methods are in charge of preserving the network's pathways and ensuring dependable multi-hop communication. The energy-efficient routing methods LEACH and DEEC in WSNs were described in this study.
