“…The nodes can localize themselves using any localization technique proposed for UWSNs, as explained in [18,19]. We assume that the underwater nodes transmit packets using a CSMA-based channel access scheme such as Slotted-FAMA [20], R-MAC [21], T-Lohi [22], SF-MAC [23], BroadcastMac [24], and HRMAC [25] in jamming-less UWSN environment. The maximum transmission power (E nrml ) of each node is fixed and the transmission range (R nrml ) is circular in shape with sharp boundary, which is defined by the respective RSS threshold.…”

“…By this manner, ordered CSMA can achieve higher channel utilization than TDMA. Fan et al improved ordered CSMA in [13], and a new protocol called hybrid reservation-based MAC (HRMAC) has been proposed. In HRMAC protocol, the nodes first reserve the channel before transmitting their data packets in a given order.…”

Underwater acoustic local area networks (UA-LANs) can be used to improve the coverage of an underwater network by introducing a tier of local area communications. Media access control (MAC) is a crucial issue for UA-LANs. Existing MAC protocols for terrestrial WLANs cannot be directly applied to UA-LANs due to the acoustic channel features of limited bandwidth and high and variable propagation delay. In this paper, we propose a handshake based ordered scheduling MAC (HOSM) protocol for UALANs. The nodes with data packets to be transmitted first reserve the channel in a channel reservation phase. Then an order list is calculated, and the data packets of these nodes are transmitted according to this order list. We develop a control packets transmission adjustment mechanism to reduce collisions of control packets. The key idea of this mechanism is to utilize the information of propagation delay to adjust the time instant of control packets transmitting. To improve channel utilization, we present a variant Max-Min Ant System algorithm to calculate an optimal order for each data transmission round. Simulation results have confirmed that the proposed protocol can achieve high throughput with low delay and good spatial fairness.

“…They presented a closed-loop distributed algorithm to optimize the transmit power and the code length jointly. Fan et al [16] proposed a hybrid reservation-based MAC (HRMAC) protocol for UASNs. HRMAC has a circle period which is divided into notice period (NP), order period (OP), data period (DP), and reply period (RP).…”

We propose an underwater CSMA/CA protocol with multi-RTS and multi-DATA receptions using the long underwater propagation delay. We analyze the throughput and delay of the proposed underwater CSMA/CA protocol through a ring-based underwater network modeling. The proposed protocol does not need to maintain the information of internode propagation delay for each pair of underwater nodes. In the proposed protocol, when there are simultaneous transmissions of RTS frames from different underwater sensors to an underwater sink as their back-off counters reach zero, the sink can recover some RTS frames which are not overlapped at the sink in the time domain due to the long underwater propagation delay. Then, the sink transmits CTS frame containing the DATA transmission order and the IDs of the sensors which transmitted the recovered RTS frames. Sensors which correspond to the IDs contained by the CTS frame can transmit DATA frame to the sink according to the DATA transmission order. We evaluate the throughput and delay performance of the proposed protocol with varying the number of sensors and the contention window size compared to the conventional protocols. The analytical results agree with the simulation results well for the proposed protocol with various numbers of sensors and contention window sizes. The analytical and simulation results show that the proposed protocol outperforms the conventional protocols.
