An Efficent Coverage and Maximization of Network Lifetime in WSN Through Metaheuristics

<span>In wireless sensor networks (WSNs), energy, connectivity, and coverage are the three most important constraints for guaranteed data forwarding from every node to base station. Due continuous sensing transmission tasks, nodes deplete more quickly hence they seek help of nodes, called relay nodes. However, a given set finding optimal locations place is very challenging problem. Moreover, earlier studies, placement defined as non-deterministic polynomial tree hard (NP-Hard) To solve this problem, we propose multi-objective firefly algorithm-based (MOFF-RNP) deploy an number while considering coverage, energy constraints. achieve network lifetime, work adopted harvesting capabilities backup strategy such that always connected at least one forward data. The formulated objective function MOFF applied better solution. Extensive Simulations carried out over proposed model validate performance obtained results compared with state-of-art methods)</span>
