“…It is assumed that the network does not vary at a rate faster than a round trip time. In E-PULRP, rather than using separate transmissions, flooding or repeating the layering process, an implicit re-layering scheme, exploiting the transmission of various control packets in the communication phase, is used [1]. Such a scheme would reduce latency and communication overhead which are generally due to explicit acknowledgement mechanisms.…”

A novel Energy optimized Path Unaware Layered Routing Protocol, E-PULRP has been proposed for a densely deployed 3D UWSN in [1] where a uniform distribution of underwater sensor nodes was considered. A stationary sink node was assumed to be located at the center of the deployment volume.…”

Abstract-Energy optimized Path Unaware Layered RoutingProtocol (E-PULRP) for dense 3D Underwater Sensor Network (UWSN) is proposed and analysed in this paper. In the proposed E-PULRP, sensor nodes report events to a stationary sink node using ℎ routing. E-PULRP consists of a layering phase and communication phase. In the layering phase, a layering structure is presented wherein nodes occupy different layers in the form of concentric shells, around a sink node. The layer widths and transmission energy of nodes in each layer are chosen taking into consideration the probability of successful packet transmission and minimization of overall energy expenditure in packet transmission. During the communication phase, we propose a method to select intermediate relay nodes ℎ , for delivering packets from the source node to sink node. We develop a mathematical framework to analyse the energy optimization achieved by E-PULRP. We further obtain expressions for throughput, delay and derive performance bounds for node densities and packet forwarding probabilities, for given traffic conditions. A comparison is made between the results obtained based on simulations and analytical expressions. The energy efficiency is also demonstrated in comparison with existing routing protocol for underwater sensor networks.Index Terms-Under sensor networks, energy aware routing, end-to-end throughput.

“…Underwater sensor networks find applications in oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation, tactical surveillance, and mine reconnaissance [Zorzi et al, 2008]. So as for an UWSN to be best designed and fully operable for the afore-mentioned applications, there are certain challenges, due to the peculiarities of the medium that should be taken into account [Huang et al, 2009;Gopi et al, 2008;Hu, and Fei, 2010;Xie et al, 2010]. These are presented as follows:…”

Sensor networks in underwater environments face unique adverse conditions. In order to be functional, specialized routing protocols are required to route the data from source to destination. This paper surveys routing protocols for underwater sensor networks. The routing protocols are examined and compared with respect to the network conditions and quality measures such as packet delivery ratio, average packet delay, energy consumption among others. Advantages and disadvantages of each routing protocol are pointed out.
