Abstract
In geographically dense and energy-limited wireless sensor networks, connectivity-based localization with full power transmission can be inefficient in terms of energy consumption. In this letter, we propose a distributed power control-based connectivity reconstruction game, which considers both energy efficiency and the quality of localization. The proposed scheme results in a better performance with an improved 61.9% reduction in energy consumption while maintaining the performance of localization at a level similar to the conventional algorithm with full-power transmission.
