“…In the field of UASNs, J. Xiong et al in [29] proposed to arrange the timetable according to the data priority. H. Cho et al in [30] proposed a protocol to grade the data in advance, and then allocate channels and make the transmission order according to the data priority to improve resource utilization of the system. In [31], we proposed a data importance rating routing (DI2R) protocol for UASNs, where we take not only the data importance rating, but also the residual energy of sensor node and packet loss probability into account.…”

“…In addition, the protocol uses short ranges of underwater acoustic communication links to achieve higher throughput. In [18], Cho et al propose a PR-MAC protocol, in which nodes exchange information between 2hop neighbor nodes in random accesses period. According to predetermined priority, each node is assigned transmission opportunities with contention free method by TDMA scheme.…”

“…Some of these solutions applying duty cycle mechanism (switching to sleep mode periodically) to reduce energy consumption since sensor nodes consume less energy in sleep mode. In traditional WSN, such a mechanism is widely adopted to conserve energy (Chao and Lee, 2012;Ye et al, author (Azar and Manzuri, 2010;Guo et al, 2009;Molins and Stojanovic, 2006;Ng et al, 2010;Park and Rodoplu, 2007;Syed, Ye, et al, 2007;Syed et al, 2008;Yang et al, 2011) (Chen and Wang, 2007;Cho et al, 2011;Diamant et al, 2011;Hong et al, 2008;Ma et al, 2009) multichannel (Chao and Wang, 2012;Chao and Lu, 2011) 2004); however, in UWSN, we do not find many protocols adopt this duty cycle mechanism yet. UWAN-MAC (Park and Rodoplu, 2007) and the one proposed by Azar et al (Azar and Manzuri, 2010) are two solutions that have applied duty cycle mechanism for power saving.…”

“…In a lightly loaded environment, the performance gain may not compensate for the overhead and thus, these protocols are suitable for heavily loaded environments. There are some single-channel, contentionfree protocols for UWSN (Chen and Wang, 2007;Cho et al, 2011;Diamant et al, 2011;Hong et al, 2008;Ma et al, 2009). These protocols either operate in a singlehop environment or require the information of relative distances/propagation delays among nodes.…”
