ABSTRACT
Along with handling and poor storage capacity, each sensor in wireless sensor network (WSN) is equipped
with a limited power source and very difficult to be replaced in most application environments. Improving
the energy savings in applications for wireless sensor networks is necessary. In this paper, we mainly focus
on energy consumption savings in applications for wireless sensor networks time critical requirements. Our
Paper accompanying analysis of advanced technologies for energy saving techniques for the optimization
of energy efficiency together with the data transmission is optimal. Moreover, we propose improvements to
increase energy savings in applications for wireless sensor networks require time critical (LEACH
improvements). Simulation results show that our proposed protocol significantly better than LEACH about
the formation of clusters in each round, the average power, the number of nodes alive and average total
received data in base stations.
