“…Our simulations use the QualNet simulator to replicate the behavior of a real network. As simulations are prone to errors, the QualNet simulation serves as an independent confirmation of work undertaken in ns-2 by other researchers [2][3][4]. Simulating well known protocols also enhances our confidence in later results from the tool.…”

Underwater acoustic networks (UWANs) offer potential in a wide range of applications, but conventional MAC protocols do not work well due to the long propagation delays relative to packet duration. Even for some innovative MAC protocols that show promise, there remains much uncertainty as to their actual performance under anything other than carefully selected scenarios. In some cases the only published results are simulations undertaken by the protocol proposer, resulting in a lack of independent verification. In this paper we detail independent simulation results for several MAC protocols in underwater acoustic networks, compare these to previously published results and accepted theory and analyze the impact of the large propagation delay on different protocols. The limitations of existing published simulations are then addressed, providing a basis for improved simulations in the future. Finally we review progress towards validation of acoustic MAC simulations, and highlight ways in which real-world tests can be improved.

This study aims at analyzing the performance of protocols designed for the control of Medium Access in the underwater environment using Underwater Acoustic Wireless Sensor Networks (UW-ASNs). Oceans today, are playing an eminent part in monitoring climate, storing and releasing Carbon dioxide, supplying foodstuffs, and shipping. The sectors that can benefit most from this research are industries dealing with oil and gas, fisheries, UW instrumentation, armed forces, research and exploration bureaus, etc. Existing terrestrial Wireless Sensor Networks (WSN) Medium Access Control (MAC) protocol which mostly use radio waves for communications are unsuitable for underwater atmosphere. Underwater sensor networks (UWSNs) using acoustic wireless networking finds application in the supporting tools for such applications. The unique properties of the UW acoustic communication path necessitate the need for new efficient, reliable MAC protocols to meet the challenges of propagation delay, multipath and fading and excessive power absorption at higher frequencies etc. Owing to the typical properties of acoustic wave propagation in the underwater atmosphere, the energy efficiency in UW-ASN is badly affected by the long propagation delay and data packet collisions, which hinders the transmission of the data packets that enables us to achieve collective monitoring tasks. This paper, present MAC protocols tailored for UWANs, the classification of MAC protocols, the state of the art, environment characteristics, challenges, and performance metrics in terms of throughput, propagation delay, energy consumption and quantitative analysis of some selected protocols. It also gives an insight of some challenges and open issues for future works. The analysis was made on UAN-CW-MAC protocol and UAN-Aloha, to understand the shape of the throughput curves for the protocol. The simulations were performed on network simulator ns3 to obtain the throughput curves for uan-cw mac with 20 nodes and uan-Aloha with 2-15 sensor nodes with one sink. The results obtained are shown for 20 simulation runs for each node.

“…Case 2-b: T max p > 2T t In sub-region 1, 0 ≤ r ≤ T t v, P S 1b is given by (9). In sub-region 2, T t v < r < R − T t v. If n additional frames from neighboring transmitters are generated, of which n are from a distance r such that R ≥ r ≥ r + T t v and n − n are from a distance r such that 0 ≤ r ≤ r − T t v, the intended frame to the receiver will still be successful.…”

“…In another work [9], communication between a master (gateway) node and the slave (non-gateway) nodes was considered, where separate channels for control (reservation) and data were suggested in RTS/CTS handshake based reservation protocol. The RTS frames from the non-gateway nodes are sent using the Aloha protocol, and until a desired CTS frame is received at a non-gateway node, it does not transmit its data frame.…”

This paper provides an analytic framework of Aloha and slotted Aloha (S-Aloha) performance in an underwater one-to-one communication environment with high and random inter-nodal signal propagation delay. The analysis shows that random inter-nodal propagation delay has no effect on the underwater Aloha performance. It also sheds light on the throughput degradation of underwater S-Aloha with a slotting concept that achieves terrestrial S-Aloha equivalent one-slot vulnerability. Additionally, a new, modified slotting concept is introduced where the slot size is judiciously reduced such that even by allowing some collisions the overall system throughput can be increased. Our numerical and simulation results show that, with the modified slotting approach up to 17% throughput performance gain can be achieved over the naive (terrestrial S-Aloha equivalent) slotting approach.
