Wireless sensor networks (WSNs) consist of self-governing sensors that sense as well as monitor the area in which these nodes are deployed and distribute this information in a distributed manner. Presently, the WSN with long life and minimum energy consumption are in demand. To overcome this problem, Low Energy Adaptive Clustering Hierarchy (LEACH) is presented with the addition of Cuckoo Search (CS) and Support Vector Machine (SVM) concept. The problem of LEACH protocol like which node is

... dered as Cluster Head (CH) is overcome by CS. On the basis of healthy function, the nodes property such as energy consumed by each node is categorized. Those nodes that have higher energy compared to the defined function are put in one category and remaining in another category. These two categories of nodes are provided as an input to SVM and train the system. Therefore, the best node having the highest energy is considered as CH and hence enhanced the lifetime by saving the energy upto 21.86 %.
