Wireless sensor network (WSN) is a network consisting of small nodes with sensing, computation and capabilities of wireless communication. Nodes collect, transmit and forward data to base station. It is a hot emerging technology. Each sensor fetches data from the monitored area like temperature, sound, vibration, pressure etc. In WSN energy constraints makes energy saving and make longer the network lifetime. In this paper we reviewed different approaches of LEACH proposed by different researchers relating to clustering and scheduling of wireless sensors. In this paper, we done the comparison the various protocols of LEACH and its parameters are energy efficiency, Lifetime of networks etc.
