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 کاملmac protocols in underwater wireless sensor networks: issues and simulations
underwater acoustic wireless sensor network (uawsn) use acoustic signalsto transmit data. acoustic signals in underwater environment have high bit errorrate, long propagation delay and limited bandwidth. another constraint in uwasnis energy. due to these constraints, design of energy and bandwidth efficient andpropagation delay aware mac protocol is a great challenge in uwasn.underwater sensor ...
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...
متن کاملAnalyzing Multi-channel MAC Protocols for Underwater Acoustic Sensor Networks
The focus of this paper is on the multi-channel MAC protocols for underwater acoustic sensor networks. We model and analyze two generalized multi-channel MAC protocols: multi-channel access with Aloha on a dedicated control channel and multi-channel access with RTS/CTS on a dedicated control channel. Though the long delay feature of underwater acoustic channels drastically increases the complex...
متن کاملA Reliable and Efficient MAC Protocol for Underwater Acoustic Sensor Networks
Underwater acoustic sensor networks (UWASNs) are playing a key role in ocean applications. Unfortunately, the efficiency of UWASNs is inferior to that of the terrestrial sensor networks (TWSNs). The main reasons are follows: (1) UWASNs suffer long propagation delay; (2) UWASNs are limited by the narrow bandwidth. Many MAC protocols are proposed to improve the efficiency of UWASNs. However, thei...
