A MACA-based MAC protocol for Underwater Acoustic Sensor Networks
The medium access control (MAC) protocol design of underwater acoustic sensor networks (UWASNs) faces many challenges: the power limitation at nodes, long propagation delay, low data rates, etc. These challenges of underwater acoustic channels result in the unsuitable usage of terrestrial networks MAC protocol in UWASNs. Moreover, the long propagation delay causes a serious problem for the MAC ...
متن کاملMedium Access for Underwater Acoustic Sensor Networks
The underwater acoustic channel has many fundamentally different properties to the conventional radio-based wireless channel. Communication is changed drastically by acoustic propagation speeds that are five orders of magnitude slower than radio. This, coupled with bandwidth limitations, high transmit energy cost, complex multi-path effects, and high bit-error rates make the issue of medium acc...
متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

متن کاملMulti-channel MAC Protocols for Underwater Acoustic Sensor Networks
Medium Access Control(MAC) protocol is quite important to the performance of underwater sensor networks(UWSNs). Recently, much research work has been done on the design of new MAC protocols for UWSNs to improve throughput and energy efficiency [1]–[3]. All these work is for the singlechannel network scenario. However, the fast development of underwater acoustic communication technologies enable...
