Wireless sensor network is not fixed infrastructure which contain either homogenous or heterogeneous sensor node. Each node have own residual energy .So it’s very important factor of network to prevent the energy of nodes, so that nodes alive more and network establishment in long time without disturbance. LEACH is one of hierarchical routing protocol which is use for secure the energy. For past few year , develop many algorithm to improve the hierarchical routing protocol so improve the overall network and minimize energy consumption ,which includes new algorithm based on clustering based genetic algorithm i.e. Low Energy Adaptive Clustering hierarchical –cluster based genetic algorithm(LEACH-GAC) and also research on security in cluster so unauthorized not access so private data easily transfer and received into cluster. Compare with LEACH-B,LEACH-C,LEACH-GA,LEACH-GAC varying with residual energy, Cluster formation, security
