摘要: The Underwater Acoustic Sensor Network (UASN) is a network which consists of underwater wireless sensor nodes distributed randomly over the certain area observation and communicate with each other using acoustic signals. UASN can be used in wide variety applications, ranging from marine biology surveillance to earthquake tsunami alert applications. Despite fact that networks are meant collect data, some collection data without location occurrence becomes incoherent. Hence, localization for has become an enthralling research topic recent years. However, there several disadvantages channel like propagation delay, limited energy sources, high bit error rate, harvesting techniques make very challenging. Therefore, this paper we have proposed scheme employs two-way time arrival estimation method calculate distance avoid requirement synchronization
