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 کاملA 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 کاملGame Theory based Energy Efficient Hybrid MAC Protocol for Lifetime Enhancement of Wireless Sensor Network
Wireless Sensor Networks (WSNs) comprising of tiny, power-constrained nodes are getting very popular due to their potential uses in wide applications like monitoring of environmental conditions, various military and civilian applications. The critical issue in the node is energy consumption since it is operated using battery, therefore its lifetime should be maximized for effective utilization ...
متن کاملPBA: A New MAC Mechanism for efficient wireless communication in Underwater Acoustic Sensor Network
There are considerable serious propagation delay rate and high error rate in case of data transmission in the poor and causal environment, such as underwater. Like this environment usually has heavy fluctuation of error rate and limited wireless communication state. Therefore, mechanism using in such environment has to be efficient and simple. This paper suggests a novel block ack mechanism, ca...
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...
