Energy Efficient in Wireless Sensor Networks Using Cluster-Based Approach Routing

In wireless sensor networks, the energy consumed by each node of the network influences the lifetime of the networks, more than the consumption of energy increases more than the lifetime of the networks decreases, this is why the increase of the lifetime of the networks requires a strategy (protocol) which reduces the power consumption of the transmission or reception of data by the sensor nodes. In recent years much research has been done to maximize a life time of network sensor. To deal with this, the hierarchical protocols (Cluster based-approach, chain based-approach) have been developed in order to reduce the network traffic toward the sink and therefore prolong the network lifetime. In this paper, the focus is mainly driven over the survey of the energy-efficient using hierarchical cluster-based approach namely LEACH (Low Energy Adaptive Clustering Hierarchy Protocol), in order to propose a new method to maximize more the life time of network sensor. Our method is to conserve energy consumption when transmitting data to the Base Station (BS). We evaluated the performance of the LEACH protocol with our proposed method simulated, the results of our method are demonstrated by the simulation results using Matlab Simulink.
