Abstract
One of the key issues in large wireless sensor networks is a precise position determination of every node with minimal hardware requirements and lowest energy consumption. Exact localization techniques, which are prone to input errors, are resource-intensive and not feasible on simple sensor nodes without adaptations. The key mechanism is to effectively split the complex computation and distribute the communication load across all nodes. Therefore, we present the least squares (DLS)-algorithm. DLS is a resource-aware localization method that achieves 47% computation savings and 86% energy savings compared to the reference method, a fully distributed multilateration on every sensor node.
