Along with handling and poor storage capacity, each sensor in wireless sensor network (WSN) is equippedwith a limited power source and very difficult to be replaced in most application environments. Improvingthe energy savings in applications for wireless sensor networks is necessary. In this paper, we mainly focuson energy consumption savings in applications for wireless sensor networks time critical requirements. OurPaper accompanying analysis of advanced technologies for energy saving techniques for the optimizationof energy efficiency together with the data transmission is optimal. Moreover, we propose improvements toincrease energy savings in applications for wireless sensor networks require time critical (LEACHimprovements). Simulation results show that our proposed protocol significantly better than LEACH aboutthe formation of clusters in each round, the average power, the number of nodes alive and average totalreceived data in base stations.
