Mobile Wireless Sensor Networks (MWSNs) are widely used in applications such as environmental monitoring, disaster management, military surveillance, and smart city infrastructure. Accurate localization of sensor nodes is essential for reliable data collection and network coordination. However, localization accuracy is often degraded by adverse conditions such as node mobility, signal interference, environmental obstacles, and limited energy resources. Many existing localization algorithms improve positioning accuracy but result in high energy consumption due to frequent communication and computation. This study examines energy- efficient localization techniques designed to improve node position estimation while minimizing energy usage in mobile sensor networks. The proposed approach integrates adaptive localization strategies, RSSI-based distance estimation, and mobility prediction mechanisms to maintain localization accuracy under unfavorable conditions. Results from previous studies reported in scholarly literature indicate that energy-aware localization algorithms can significantly reduce communication overhead while improving network lifetime and positioning accuracy in dynamic sensor environments.
