Abstract : Design and Implementation of MAC and PHY for UW - ASN ( Underwater Acoustic Sensor Network ) *

WSN (Wireless Sensor Networks), one of the most popular topics in wireless and mobile networking, is gaining much interest as an innovative technology in the near future. Especially in UW-ASN (UnderWater-Acoustic Sensor Network), there are many potential applications that can be provided through the networks such as ocean sampling network, environment monitoring, undersea exploration, disaster prevention, assisted navigation [1]. But the peculiarities of the physicals phenomena in ocean cause some challenges for the scientists when designing the UW-ASN [2]. These points require suitable architecture for underwater sensor network, especially in MAC protocol. We will focus on introducing the design and implementation of UW-ASN system in Section 2, and analyze the results of the experiments in a preliminary testbed in Section 3. The paper will conclude with the conclusion and future work in Section 4.
