ABSTRACT
Since the development of the wireless sensor network (WSN), energy efficiency has been the major concern of the researchers. Various techniques have been proposed in the literature which has focused primarily on utilizing the energy efficiency issue of the sensor nodes. However, the location of the nodes which are continuously consuming their energy must be known for acquiring the precise information about the network. Therefore, it is crucial to determine the location of these sensor nodes. There is a provision of adding GPS module to the sensor nodes, but this adds a huge cost to the network that becomes unaffordable when made to implement over large areas. To address this concern, in this chapter we have used the Bat algorithm (BA) to localize the target nodes by using the anchor node moving in the Hilbert curve path. The simulation results reveal that the proposed scheme, i.e., Localization using BA (LBA) outperforms various other localization techniques in terms of reducing localization error and also convergence period. LBA is very useful for applications where nodes are deployed in remote locations, as the critical information can be acquired from that particular location with the least localization error.
