Abstract
One of the most important criteria for creating any real-time wireless sensor application in challenging ad hoc networking environments is energy efficiency. In places like steep terrain, woods, seas, or marine habitats, wireless sensor nodes are widely dispersed. It becomes vital to have energy-efficient performance in sensor nodes, which may be evaluated in terms of routing, coverage, and connection, since physical access to the nodes placed in this region or human interaction constitutes a significant annoyance. These are the criteria that allow us to determine how well the distribution of sensor nodes covers the region. A comparative research and analysis of many energy-saving strategies for wireless sensor networks is presented in this article.
