Abstract: All data collected by the sensor nodes is sent to sink nodes in the Wireless Sensors Networks (WSNs). Therefore, location and the optimal number of the sink nodes has a significant impact according to the various complexity factors, it can be addressed with optimization algorithms as an optimization problem. In this study, a Multi-Objective Modified Flower Algorithm (MOMFPA) pollination has proposed to deal with the problem of multiple sink nodes in WSN in order to attain the minimum number of multiple sink nodes with reduced energy consumption to extend the lifetime of the WSN. To realize this, a fitness function has been formulated to guarantee the balance between the sink nodes and energy consumption. Moreover, to assess the performance of the proposed algorithm introduced here, it is simulated in different network sizes ranging from 100-5000 nodes and the results proved that the proposed algorithm overcomes the two well-known algorithms famous in the optimization domain such as Multi-Objective Differential Evolution (MODE) and Multi-Objective Particle Swarm Optimization (MOPSO) in terms of the number of multiple sink nodes as well as the low energy consumption. Eventually, the quantitative and qualitative results revealed that the proposed MOMFPA significantly was able to find the optimal Pareto Front (PF) and provide a superior quality of solutions.
