Energy consumption is the core issue in wireless sensor networks (WSN). To generate a node energy model that can accurately reveal the energy consumption of sensor nodes is an extremely important part of protocol development, system design and performance evaluation in WSNs. In this paper, by studying component energy consumption in different node states and within state transitions, the authors present the energy models of the node core components, including processors, RF modules and sensors. One of the major issues in wireless sensor networks is developing a routing protocol which has a significant impact on the overall lifetime of the sensor network. This paper presents a new version of LEACH protocol called MODLEACH which aims to reduce energy consumption within the wireless network. The proposed protocol uses simulation model. The simulation tool we used for the purpose is MATLAB. Simulation results show that the New Improved MODLEACH routing protocol reduces energy consumption and increases the total lifetime of the WSN compared to the LEACH protocol.
