In wireless sensor network, it is an important task to collect the data periodically from various sensors node for monitoring and recording the physical conditions of the environment. The sensed data must be transmitted and received between the nodes in the network. The Low Energy Adaptive clustering hierarchy (LEACH) is one of the routing protocol to transmit the data between the nodes in the network. In this work, LEACH protocol is modified and developed the new concept called MLEACH. The proposed protocol is energy efficient for heterogeneous network. The performance was analyzed by considering the time period and it shows that the number of alive nodes was less. Since the alive node is less the energy consumption is also less and thereby increasing the energy efficiency of the network. The comparative analysis was made between the existing and the proposed method. Simulation result shows that the proposed method is more energy efficient than the existing LEACH protocol.
