Recent energy-preservation endeavours for longlife wireless sensor networks: A concise survey

Energy consumption remains the dominant limitation in most sensor networks. An outsized and growing body of literature has investigated the energy-efficiency problem. In general, energy is afforded either through preserving the already allocated energy sources such as batteries or super-capacitors; or through harvesting energy from the environment; or by utilizing both approaches. In this paper, we highlight the recent research efforts for saving the allocated energy. A unique taxonomy of energy-saving techniques dedicated to sensor networks is provided. Therefore, this paper represents an excellent source for new researchers in this field. Moreover, we present our recent developed approaches within the same context including exploiting the concepts of virtual detection and Fuzzy transform for optimizing the power consumed by sensing and radio communication units, respectively.
