“…On the other hand, UWAN may be affected by the uncertain space and time due to the high latency environment [3]. Traditional handshake mechanism often used three-way RTS/CTS/DATA, which resulted in the delay, and then low channel utilization [4]. To solve this problem, Chirdchoo et al proposed a three-way handshake protocol MACA-MN.…”

Studies on MAC protocols of the Underwater Acoustic Sensor Network (UASN) are very important due to wide application area and great application potential of UASN. In this paper, a new concurrent bidirectional MAC protocol based on receiver self-adaption (RABIC-MAC) is proposed to improve the data transmission efficiency and reduce the overhead. Then the throughput and the End-to-End delay are calculated, and then compared with the BIC protocol. Results show that the saturated throughput is larger 16.7 % and 33.0 % for 4200 and 6125 m, respectively, than the BIC. The saturated End-to-End delay is larger 13.0 % and 20.0 % for 4200 and 6125 m, respectively, than the BIC. Therefore, the RABIC-MAC evidently improves performances of UASN.

“…; g iK Þ is referred to as the encoding vector for encoded packet Y i [9] and is carried in the packet as overhead. We choose K 0 P K since adding a small amount of redundancy at the source (e.g., K 0 ¼ K þ 2) reduces the impact of lost packets at the first hop (which cannot be recovered at later hops) 2 and improves error recovery at the sink [7].…”

“…However, the characteristics of UWSNs, such as low bandwidth, long propagation delays and high error probability, are significantly different from those in terrestrial sensor networks. These unique characteristics pose a range of challenges [2][3][4][5][6]. One such challenge is efficient error recovery when using underwater acoustic channels.…”

“…Despite years of research, many critical underwater applications, such as oceanographic data collection, pollution monitoring, tactical surveillance applications, remain quite limited. The studies of [2][3][4][5][6] survey fundamental constraints, potential applications, challenges and future research directions in underwater environments. They point out that one ideal vehicle for these aquatic applications is underwater sensor network (UWSN) [4].…”

Abstract. One of the main appeals of mobile sensors is the variety of environments in which they can operate as an autonomous network. Different environments, however, present different challenges, especially in terms of inter-sensor communication. In sparse environments, it may not be possible to maintain full connectivity at all times, setting off the need for agents to communicate opportunistically when they are close to each other. This, in turn, suggests that communication needs be taken into account in the design of agents' trajectories. In this paper, we introduce a notion of tour and meeting point as an abstraction of trajectories designed for both sensing and communication, and we study the tradeoffs involved between motion to sense and sample and motion to communicate and interact.
