摘要：The objective of WSN (Wireless Sensor Network) is not only to do data communication but also toincrease the network lifetime by retaining the energy of nodes for the longer period. To achieve this objective gridclustering is used for clustering the entire sensor network in equal size square grid,where each grid is a cluster, afterthat closeness centrality is utilized for cluster head selection, which is based on the distance criteria, as energyconsumption is directly proportion to square of distance, hence this centrality approach will select the cluster headwhich is at the minimal distance from other nodes in the grid, hence minimize the energy utilization. For routing, BFOwhich is a bio inspired algorithm is utilized, by considering energy and distance in its fitness function. Among all theoptimization techniques, BFO is preferred as it can provide optimal solution for any multi- objective function.Simulation is done in MATLAB and it is observed that proposed algorithm outperforms the existing one in terms ofretaining number of alive nodes for more number of rounds, hence increase the network lifetime,and have longerstability period.
