摘要：Underwater Wireless Sensor Networks (UWSNs) are widely used to explore aqueous environment. In UWSN, determining the location of sensor nodes is a critical issue. Sensed data is meaningful only when sensing node is localized. There are many techniques available for localization in Wireless Sensor Network (WSN) but they are not applicable in UWSN. GPS signals cannot be used underwater for localization. Underwater communication is based on acoustic waves. This paper explores the different localization schemes available for UWSN and challenges to meet the localization issue. Node mobility, high propagation delay, time synchronization and high bit error rate are the main challenges that need to be addressed.
