The nodes in a Wireless Sensor Network (WSN) are generally grouped in clusters to improve the longevityand efficiency of the network. Since the nodes have limited power capabilities and finite computation power, it becomesimperative to design algorithms to conserve the limited resources of the WSN in order to enhance the up time of thenetwork.In this paper, a revised version of Ant Colony Optimization based LEACH protocol (RA-LEACH) is compared withLEACH protocol [1], with focus on the energy consumption by the nodes. The proposed RA-LEACH protocol whileelecting Cluster Heads (CHs) takes into consideration the following parameters – the ratio of the residual energy at eachnode with its original energy and the ratio of the distance of the node from the Base Station (BS) with the distance of thefarthest node.From the simulation results, it is evident that change in the threshold calculations, improves the original design ofLEACH algorithm in terms of minimizing energy consumption and improving the network lifetime.
