“…Also, the time slot allocation for individual nodes becomes hard to manage when the number of nodes grow. Guo et al introduce the propagation-delaytolerant collision avoidance protocol (PCAP) in [8], which is a handshaking-based protocol. It also requires clock synchronization between neighboring nodes, just like those in [12].…”

Abstract-Although there are many MAC protocols that have been proposed for terrestrial wireless networks with a wide variety of aspects, these protocols cannot be applied directly in underwater acoustic networks due to the channel's uniqueness of having low data rate and long propagation delay. In order to achieve a high throughput, both characteristics must be taken into account in the MAC design. We propose a random access MAC protocol for multi-hop underwater acoustic networks based on receiver reservation, which we shall call the "Receiverinitiated Packet Train" (RIPT) protocol. It is a handshakingbased protocol that addresses the channel's long propagation delay characteristic by utilizing receiver-initiated reservations, as well as by coordinating packets from multiple neighboring nodes to arrive in a packet train manner at the receiver. Our simulation results have confirmed that the RIPT protocol can achieve our goal of having high and stable throughput performance while maintaining low collision rate.

“…The long propagation delay, on the other hand, makes it very expensive to transmit multiple control packets (e.g., RTS/CTS frames) before every data packet transmission. In fact, both [8] and [9] have shown that such a technique offers a lower throughput than the well-known Aloha protocol when applied in underwater acoustic networks.…”

“…Since underwater sensor nodes (UNs) compete with each other to occupy the common acoustic communication channel formed by the propagation of the slow sound waves, the contention-based MAC protocols [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] suffer from the collision risk. The collision probability of the contention-based MAC protocols is increased as the traffic load increases.…”

Asymmetric Propagation Delay-Aware TDMA MAC Protocol for Mobile Underwater Acoustic Sensor Networks

et al. 2018

Abstract:The propagation delay in mobile underwater acoustic sensor network (MUASN) is asymmetric because of its low sound propagation speed, and this asymmetry grows with the increase in packet travel time, which damages the collision avoidance mechanism of the spatial reuse medium access control (MAC) protocols for MUASN. We propose an asymmetric propagation delay-aware time division multiple access (APD-TDMA) for a MUASN in which periodic data packet transmission is required for a sink node (SN). Collisions at the SN are avoided by deferring data packet transmission after reception of a beacon packet from the SN, and data packets are arrived at the SN in a packet-train manner. The time-offset, which is the time for a node to wait before the transmission of a data packet after reception of a beacon packet, is determined by estimating the propagation delay over two consecutive cycles such that the idle interval at the SN is minimized, and this time-offset is announced by the beacon packet. Simulation results demonstrate that the APD-TDMA improves the channel access delay and the channel utilization by approximately 20% and 30%, respectively, compared with those of the block time bounded TDMA under the given network conditions.

“…Light waves and frequency are not as much suitable due to the high absorption, attenuation and scattering as there is very large area for monitoring in sea so distance transmission creates problems [5]. UWSNs are used for the monitoring requirement of aqueous environment where the acoustic sensors gather interesting information and forward this data to the end node using any specific routing technique [6]. Figure 1 shows the general phenomena of UWSNs.…”

Abstract-Recent research has seen remarkable advancement in the field of Under Water Sensor Networks (UWSNs). Many different protocols are developed in the recent years in this domain. As these protocols can be categorized in a variety of ways according to the mechanisms and functionalities they follow, hence it becomes important to understand their principal working. In this research we have introduced three analysis methods; Clustering based, Localization based and Cooperation based routing by selecting some recent routing protocols in the field of UWSN and presented a comparative analysis according to the categories in which they lie. This research has been taken theoretically and is qualitative one. Also a detail analysis of their key advantages and flaws are also identified in this research.
