N2 - Wireless sensor networks (WSN) is presented solution for the problem of low-cost and flexible monitoring event, especially in places with limited access or dangerous for humans. Wireless sensor networks are built from wireless devices with limited resources thus to Long-Term survival of the Network must use energy-efficient mechanisms, algorithms and protocols. one of the mechanisms controlling the topology (TC), which is composed of two parts, a topology construction and topology maintenance.This paper introduces the new algorithm for energy aware topology construction based on connected dominating set, namely, algorithm EA-CDS, wich is a simple mechanism to build the distributed, energy-efficient topology, that finds optimal connected subset and removes unnecessary nodes with minimum power consumption while the network remains connected and coverage is complete.also ,to maintain network connectivity and unfailing the nodes energy that are constantly located at sending packets path along with it , the DGTERec topology maintenance algorithm is used to balance energy consumption in nodes .Evaluation results show that the EA-CDS protocol for increasing the useful lifetime of the network (Postponing the first node death) and the number of messages sent over the same two protocols (EECDS and CDS-RULE-K) has obvious advantages. To ensure that the results of Atarraya are acceptable,The performance of the proposed method is evaluated with MATLAB and output results analysis, confirmed the results of the ATARRAYA simulator.
