“…This paper proposes a comparison between the JANUSembedded MAC protocol and two other underwater network ad-hoc protocols. The first one, named Tone-Lohi [8], is based on the ALOHA strategy, while the other [9] makes use of an enhancement of the Back-off mechanism to improve throughput and collision rate. JANUS is a signaling method that uses orthogonal frequency-division multiplexing (OFDM) to transmit digital data as a sequence of tones.…”

“…In this comparison, short ping tones are used in order to reduce the CR window and maintain the power consumption as low as possible. A Back-off tuning scheme for ALOHA has been proposed in [9] to improve packet transmission and achieve better throughput. In fact, setting the Back-off parameter properly can greatly reduce the packet collision rate and increase the throughput of the whole system.…”

“…The choice of the algorithm proposed in [9] is motivated by its simplicity and, more importantly, by the fact that it targets only the Back-off mechanism, which is of particular interest for this research. Indeed, different implementations of the Back-off mechanism can drastically change the performance of a MAC protocol.…”

“…It was developed with the idea of promoting efficient channel usage, stable throughput, and low energy consumption by using short wake-up tones for channel reservation. A Back-off tuning scheme for ALOHA-based protocols was proposed in [9]. In this work, the ALOHA scheme is used with the Back-off technique for transmitting packets to achieve better throughput.…”

“…Based on the above considerations, this paper reports the results of an experimental comparison between the JANUS MAC protocol and two other protocols: the first is obtained by replacing the standard Janus Back-off mechanism with the one proposed in [9], and the other the well-known T-Lohi protocol. The main focus of the research is to evaluate the performance differences in terms of throughput and fairness.…”

The development of MAC protocols for UWSNs is a challenging task due to energy limitations, long propagation delays and low data rates. In fact, acoustic communication suffers from latencies five orders of magnitude larger than radio communication. Therefore, a naive carrier-sensemultiple-access (CSMA) MAC protocol would require a very long listen time resulting in low throughput and poor energy efficiency. Efforts have been made to define MAC protocols based on contention-free and contention-based techniques. The JANUS protocol defines a MAC protocol that has been proven to be effective in multiple conditions but few studies have investigated its energy efficiency with respect to other underwater MAC protocols. To this end, the aim of this research is to provide an experimental comparative study of several types of MAC protocols, including the one defined in the JANUS standard, in terms of energy efficiency, fairness, and throughput.
