An Efficient Mobility Based Localization in Underwater Sensor Networks

摘要: Underwater Wireless Sensor Network (UWSN) has attracted significant attention recently from both academia and industry, as it provides a promising solution to aquatic environmental monitoring exploration. Due the limitation of electromagnetic waves, underwater sensor networks utilize acoustic signals that have high error rate, propagation delay limited bandwidth for data communication. By adopting predictable mobility patterns objects, we propose scheme, called Efficient Mobility Based Localization (EMBL) determine location information node in UWSN. The proposed EMBL scheme is divided into two parts, anchor localization ordinary localization. During process, every predicts its future pattern according past known information, estimate location. simulated MATLAB compared with existing terms coverage, error, average communication cost. It found outperforms schemes.
