Wireless sensor networks are the emerging technology which is a combination of sensors, communication and computer technologies. Sensors only have limited energy resources and hence their functionality continues until their energy is drained. Because of these sensors the sensor nodes lifetime gets decreased. Thus a protocol called LEACH is proposed which uses randomized cluster head selection to reduce the energy consumption of the sensor nodes and hence the lifetime of sensor nodes can be extended. This paper addresses certain factors like energy consumption, throughput, packet received and bandwidth to prove the efficiency of LEACH protocol. Simulation results show that the increased sensor nodes lifetime is achieved by the proposed protocol when compared to other protocols.
