This document discusses energy consumption in wireless sensor networks using routing protocols. It introduces a new routing protocol called MIN-RC, which aims to balance energy consumption among sensor nodes. MIN-RC is based on the LEACH-C protocol and uses adaptive round control to adjust cluster size, head location, and round time based on network conditions to minimize energy usage. The document compares MIN-RC to LEACH-C through simulations to evaluate its ability to extend network lifetime by more evenly distributing energy consumption across sensor nodes.
