These nodes communicate wirelessly and collaboratively send data to a central system for processing.<\/p>\n<p data-start=\"393\" data-end=\"708\">Energy efficiency is one of the most critical design considerations in WSNs because sensor nodes are typically powered by batteries that are difficult or impossible to replace, especially in remote or hazardous environments. Extending the lifetime of a network depends heavily on how efficiently energy is consumed.<\/p>\n<p data-start=\"710\" data-end=\"824\">This guide explores the principles, challenges, techniques, and best practices for building energy-efficient WSNs.<\/p>\n<hr data-start=\"826\" data-end=\"829\" \/>\n<h3 data-start=\"831\" data-end=\"877\"><span class=\"ez-toc-section\" id=\"2_Components_of_a_Wireless_Sensor_Network\"><\/span>2.
