mac 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 کاملMAC Protocol Design for Underwater Networks: Challenges and New Directions
In this chapter, we focus on acoustic underwater networks, which utilize acoustic communication links to communicate between the nodes. It is wellknown that RF signals do not propagate well underwater, and the optical signals [1] are useful for short distances and under clear water propagation conditions. For long distances, the Navy has utilized acoustic communication. More recently, there has...

متن کاملMac Protocols for Monitoring and Event Detection in Underwater Networks Employing a Fh-bfsk Physical Layer
Underwater acoustic networks of fixed and autonomous nodes can be a very valuable tool in a number of situations, from environmental monitoring to emergency scenarios (e.g., ships in distress). In this paper, we compare the performance of some MAC protocols for underwater networks in typical scenarios. We consider random access protocols, which provide sufficiently high performance in case of l...
