Advancements and miniaturization with high processing capabilities in electronics enabled sensor devices which can communicate with each other easily. Increase in signal processing power and miniaturization of the device with powerful wireless communication transreceiver unit attached to this sensor unit forms a node in wireless sensor network. Collection of these sensor networks, we call them as wireless sensor networks. The nodes are autonomous in collection of the data and forward the same to data collection point, called as sink node. Sink node is responsible for further processing of the data and providing it to application. The sensor devices use power provided mostly by the batteries. When battery is exhausted then mostly node dies or becomes of no use. To avoid this failure in network, maximum research being carried out in energy saving schemes in Wireless sensor networks. In this paper, we present survey on currents trends using of Artificial Neural Network concepts in sensor networks.
