A Survey on Efficient Power Consumption in Adaptive Wireless Sensor Networks

The paper aims to give an extensive overview of the energy constraints in Wireless Sensor Networks and the power management strategies used in the literature as power efficiency is considered as the most challenging issue in WSNs. The paper opted for an investigative study of the adaptive systems that represent efficient solutions to deal with environmental and context changes in wireless sensor Networks. It provides thorough insights about how change has brought about the use of adaptive systems in WSNs. It proposes a new adaptation technique inspired from combining adaptation in different layers and can be more efficient and performing. This paper fulfills an identified need to study reconfigurable systems to achieve power efficiency, as a sensor node is power constrained.
