ABSTRACT: Wireless
technology for underwater communication possesses a wide range of potential
application, but it is still a relatively unexplored area in many aspects
concerning modems physical design. A step towards future deployment of
underwater networks is the reduction of power consumption. Therefore,
asynchronous wakeup systems need to be integrated within the physical layer
design while avoiding the use of additional transducers. This paper offers a
practical and generic solution to adapt data reception and transmission
together with asynchronous wakeup sub-systems in acoustic underwater modem
architectures using a low power and low cost solution. The proposal has been
implemented in a real prototype with success.
