Abstract: The tremendous usage of mobile nodes in wireless communication medium makes energy efficiency a fundamental requirement of Mobile Adhoc Network. Energy plays a vital role in prolonging the network life time. DFA based QOS Aware Clustering (DFA-QAC) for the Energy-aware Optimized Link State Routing protocol (E-OLSR) is used. This algorithm takes into account the mobility, residual energy of the nodes and gives major improvements regarding the number of elected cluster heads. The objective is to elect a reasonable number of cluster heads which regulates the network traffic and preserving bandwidth. The proposed scheme DFA-QAC uses modified weighted clustering technique which helps to decide the mode of each node. It can able to select the nodes having highest residual energy as a cluster head and able to switch between states. DFA based representation helps to determine the pattern of switching between various states and can able to predict average energy required for cluster formation. Reclustering mechanism helps in electing the new cluster head, when a node has entered or it has just left its cluster. The results of the proposed scheme E-OLSR perform better than the traditional AODV protocol. The performance metrics such as energy consumption. Packet delivery ratio and throughput has been analyzed in the proposed scheme.
