Energy competence is a very important study in order to find ways to prolong the lifetime of a wireless sensor network. Therefore a good routing protocol and mechanism need to be design. Cluster based architecture is a well known method to optimize the energy competence in the network and have been applied in LEACH routing protocol. However the LEACH routing protocol that used a round concept have a problem because each node will suffer its rest energy in the current round and will die in the next round due to insufficient energy management in the network. Then, we make an alteration of LEACH’s cluster-head selection algorithm by considering an outstanding energy available in each node in order to extend the lifetime of the network. It is known as the Residual Energy (ResEn) algorithm. Consequently, at the end of this paper a comparison analysis for LEACH and ResEn has been simulated using Matlab. As a result, it shows that ResEn algorithm can extended the lifetime of the network.
