Wireless Sensor Networks are usually composed of a lot of distributed sensor nodes that organize themselves into a multi-hop wireless network. Several of the main problems in wireless sensor networks are actually energy usage, lack of authentication data integrity as well as instability of load link between sensor nodes which brings down the acceptance of the sensor network. The latest communications in wireless sensor networks (WSNs) have a lot of new energy-efficient protocols especially designed, in which energy recognition is actually an important concern. Inside WSNs, many small sensor nodes are utilized as a good means of data collecting in a variety of environments. Since the sensor nodes run on the battery of power that is restricted, it's an excellent demanding goal to develop an energy-efficient routing protocol, which may lessen the delay while providing long span and high energy efficiency of network lifetime. Our proposed item is actually improved from LEACH protocol by adapting node scheduling program (active and sleep) in heterogeneous and homogeneous node topologies of WSNs, which yield better performance in energy saving and then improved network lifetime. The work carried out is presented in this thesis will be based on simulations of newly designed routing protocols, from the key routing protocol of clustering based hierarchical, routing protocol namely called LEACH (Low Energy Adaptive Clustering Hierarchy). Simulations allow for more aspects to be evaluated and more parameter values to be investigated, than what would be possible using real applications in real wireless sensor networks. Nevertheless, the accuracy of every simulation is dependent on the accuracy of the simulation models used in the developed routing protocols
