Research in underwater acoustic networks has developed quickly to support large variety of applications such as mining equipment and environmental monitoring. As in terrestrial sensor networks; reliable data transport is demanded in underwater sensor networks. The energy efficiency of error correction techniques should be considered because of the severe(More)
Variable channel conditions in underwater networks, and variable distances between sensors due to water current, leads to variable bit error rate (BER). This variability in BER has great effects on energy efficiency of error correction techniques used. In this paper an efficient energy adaptive hybrid error correction technique (AHECT) is proposed. AHECT(More)
Variable channel conditions in underwater channels have great effects on total energy consumption. This variability in channel conditions is ignored in many networking protocols. In this paper we have investigated the effects of variable channel conditions in calculating the optimum per hop distance (i.e. optimum number of relays between sender and(More)
