An Improved Energy Efficient Double Chain-based Routing Protocol using ACO

There is no adopt that WSN affects strongly different applications and technologies, but with time a rapid changing is raised in networks and communication field developments. Therefore, many constraints are shows in WSN, one of these constraints and the most affected one is energy consumption; thus, as an inevitable result, these constraints should be overcome. Improvement of routing protocols in WSN can handle these constraints proficiently. In this paper, DDIEEPB and DDIEEPB-ACO (Double chain Double sink node Improved Energy Efficient PEGASIS protocol) using ACO (Ant Colony Optimization algorithm) is proposed. Simulation in Matlab proves that compared with the core protocol PEGASIS and the supported protocol IEEPB, DDIEEPB and DDIEEPB-ACO reduces the energy dissipation, enhance node survival rate, and prolong the network life cycle. The proposed protocols show good scalability, and it is suitable for the large-scale network.
