New approach for wireless underwater identification: acoustic frequency identification (Afid)

This work focuses on presenting a new efficiency Acoustic Frequency IDentification system in the hope of improving underwater monitoring. Earth is a water planet as ocean´s covers about two-thirds of the earth surface. Such extension remains unexploited to satisfy humans´ needs. Recently, attempts grow toward invigorating monitoring aqueous environments such as oceans, rivers, lakes, ponds and reservoirs. In this paper we propose wireless identification system for underwater applications. As a versatile system we can use it in different underwater domain. We may list: The marine domain (discovery and monitoring of pollution, underwater animals), and the public one (intelligent monitoring of pool). Current studies show that there are many techniques of underwater wireless indentification, but still with a lot of short-comings due to environmental constraints. The concept of underwater AFID draws its legitimacy from RFID by realizing reversal engineering.
