Firefly algorithm based clustering technique for Wireless Sensor Networks

Clustering of nodes in Wireless Sensor Networks is a problem of concern for many researchers. The major challenge is to propose an algorithm which can optimize the values of various performance parameters like packet delivery ratio and network lifetime of a node in the network. This paper shows an implementation of firefly algorithm to perform clustering in wireless sensor networks. Simulation results have shown the improvement in the performance parameters. The network lifetime of a node is improved as the energy exhaustion is reduced while transferring data in the network.
