UW-MAC: An underwater sensor network MAC protocol
As over 70 percent of the earth’s surface is covered by water, it is desirable to deploy underwater sensor networks to support oceanic research. Under Water Sensor Networks (UWSNs) use acoustic waves and are characterized by long and variable propagation delays, intermittent connectivity, limited bandwidth and low bit rates. Energy savings have always been the primary concern in wireless sensor...
متن کاملAn Energy-Efficient MAC Protocol for Underwater Sensor Networks
Underwater sensor networks have received growing interests recently [7], [5], [4], [1]. Compared with traditional techniques used in underwater activities such as scientific exploration and commercial exploitation, underwater sensor networks empower people to monitor or detect phenomena more accurately and timely in extended areas. The medium access control (MAC) protocol is very important to t...
متن کاملAn Adaptive Slot TDMA MAC Protocol for Underwater Sensor Networks
In this study, we introduce a new media access control (MAC) protocol that adaptively changes time division multiple access (TDMA) frame size and slot duration in order to upgrade performance of underwater sensor networks. Throughput of underwater sensor networks is very low compared to a radio frequency (RF) network; the reason is a very long propagation delay and a very low bit rate. To solve...
متن کاملAbstract : 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 ...
متن کاملSBMAC: Smart Blocking MAC Mechanism for Variable UW-ASN (Underwater Acoustic Sensor Network) Environment
In this paper, several MAC scheduling methods applicable to an underwater environment are proposed. Besides, a new marine communication system model was proposed to improve the reliability of the proposed SBMAC method. The scheme minimizes transmission of control frames except for data transmission and various transmission methods and ACK methods can be used together. Simulation models are set ...
