Energy Efficient Clustering using Jumper Firefly Algorithm in Wireless   Sensor Networks
  Wireless Sensor Network (WSN) is a major and very interesting technology, which consists of small battery powered sensor nodes with limited power resources. The sensor nodes are inaccessible to the user once they are deployed. Replacing the battery is not possible every time. Hence in order to improve the lifetime of the network, energy efficiency of the net- work needs to be maximized by decreasing the energy consumption of all the sensor nodes and balancing energy consumption of every node. Several protocols have been proposed earlier to improve the network lifetime using optimization algorithms. Firefly is a metaheuristic approach. In this paper, Energy efficient clustering for wireless sensor networks using Firefly and Jumper Firefly algorithms are simulated. A new cost function has been defined to minimize the intra- cluster distance to optimize the energy consumption of the network. The performance is compared with the existing protocol LEACH (Low Energy Adaptive Clustering Hierarchy).
