Neural Network based LEACH Clustering Algorithm in WSN

Wireless sensor networks (WSNs) are very popular in the real world applications such as battlefield monitoring; estimating traffic flows, monitor the natural phenomena, environmental changes etc. The limited size of battery is the main drawback of WSN. When the battery is exhausted then the several nodes die and of no use. To remove such type of failure in the network, many researches are carried out in the energy saving scheme. Clustering is the main issue in the wireless sensor network because it enhances the network lifetime. Many optimization techniques applied while selecting the cluster head selection. Here, we present survey on the neural network based clustering concept which enhances the network lifetime of the network.
