The rise of wireless sensor networks (WSN) is one of the leading innovations that postures different breed of intrusions, vitality and better performances in the nearing decades. However, in WSN, energy plays a vital role in transmitting data between sources. Also several communication protocols are available in cluster based for energy conservation and it varies depending on its application. Among the routing protocols, LEACH is chosen so that the vitality problem can be minimized. Few enhancements to improve its efficiency and ability to deliver data without packet loss is achieved to a greater extent. Increasing their energy through Solar means will prolong the network lifetime. Different enhanced LEACH protocols are collated to increase node alive rate, packet delivery ratio, and average residual energy, throughputs. The above parameters are derived for the R-LEACH, solar powered R-S-LEACH and SLEEP LEACH. The results are obtained using Network Simulator-2.
