Energy Conservation Strategies in Wireless Sensor Networks: A Review

Wireless Sensor Networks (WSNs) consist of small devices that sense environmental and physical phenomena. WSNs have proven their high capabilities in various fields, but there are some challenges facing sensor nodes, such as limited battery power and their communication and storage capabilities. This review of recent literature on energy improvement strategies is compressed in this review paper. The concepts of WSNs, power sources, WSNs node component, Energy Saving Techniques, power consumption were extracted and clarified. Finally, the results of previous studies regarding energy improvement were extracted, discussed, and compared at the end of the paper.
