“…In [22], a new DTN protocol is proposed, named UDTN-Prob protocol, which exploits the contact duration between the nodes and their contact knowledge to increase the packet delivery ratio and decrease the end-to-end delay. In the UDTN-Prob protocol, the probabilities of the contacts between intermediate nodes and sinks are estimated based on the relevant information exchanged.…”

“…This way, it gets an opportunity to select the best from the available options. Once the timer expired, it fetches all the INFO packets from the buffer and calculates the approximate inter-contact durations employing the position and velocity information that are shared in the INFO packet using the following equation [22]:…”

“…In DataTx state, the sender first employs a packet selection technique that commences with the estimation of number of packets, ν that can be delivered within τ B epoch. Afterwards, from the buffer, only those packets are selected whose lifetimes are more than one-hop sink θ-meeting time prediction (see [22]). Note it imposes a large computational complexity with a very limited performance gain and hence, not selected in this paper.…”

The Coastal Patrol and Surveillance Application (CPSA) is developed and deployed to detect, track and monitor water vessel traffic using automated devices. Latest advancements of marine technologies, including the Automatic Underwater Vehicles, have allowed the development of this type of applications. To facilitate their operations, installation of a Coastal Patrol and Surveillance Network (CPSN) is mandatory. One of the primary design objectives of this network is to deliver adequate amount of data within an effective time period. This is particularly essential for reporting a detection and notifying the current status of an intruder’s vessel through the adverse underwater communication channels. Additionally, intermittent connectivity of the nodes remain another important obstacle to overcome to allow smooth functioning of CPSA. Taking these objectives and obstacles into account, this work proposes a new protocol, named UDTN-RS, which is developed by ensembling forward error correction technique (namely Reed-Solomon codes or RS) in Underwater Delay Tolerant Network (UDTN) routing protocol with probabilistic spraying technique. In addition, the existing binary packet spraying technique is enhanced for supporting encoded packet exchange between the contacting nodes. A comprehensive simulation campaign is performed in identifying the effectiveness of the proposed protocol. The obtained results suggest that the proposed UDTN-RS protocol can be considered a suitable alternative of the existing protocols for sparse networks like CPSN.
