In Underwater Wireless Sensor Networks (UWSNs), reliability is one of the major concerns for large number of applications. The underwater environment is very harsh and noisy. Fading is common and unavoidable, therefore achieving reliable data transfer requires innovative routing solutions. This paper presents a energy efficient cooperative routing...
Conference Paper
The acoustic environment suffers from a number of impairments which effect transmitted data reliability and integrity leads toward low-quality routing. Integral part of cooperative routing is reliable data delivery with trade-off energy consumption is high, because of multiple transmissions. In order to overcome this problem and getting advantage o...
Conference Paper
Developing an energy efficient routing protocol for underwater wireless sensor networks (UWSNs) is a challenging task due to long propagation delay, low bandwidth, high error probability, and most importantly limited energy. Unlike terrestrial sensor networks, UWSN environment is harsh. Nodes are provided with limited energy. The replacement or cha...

Wireless link quality varies significantly in underwater networks due to the presence of environmental factors such as multipath effect, attenuation, temperature salinity and node mobility etc. Shortest path or shortest hop based underwater routing protocols often choose capricious links and hence exhibit inefficient performance. Moreover, selectio...
Article
A number of routing protocols have been proposed for underwater wireless sensor networks (UWSNs). However, most of their routing protocols do not take into account the environmental information like water depth since the shallow and deep water have different characteristics. In this article, we present an environment-aware routing protocol (named E...

Energy efficiency in Underwater Acoustic Sensor Network (UASN) is a key challenge for extending network lifetime. Base on analysis of energy consumption for LEACH in underwater channel, we propose a novel clustering scheme for UASN based on grouping nodes to ensure that nodes balance energy load by considering residual energy of candidate nodes. We...
Conference Paper
Multi-hop communication in Underwater Acoustic Sensor Network (UASN) brings new challenges in reliable data transmission. Recent work shows that data collection from underwater sensor nodes using Autonomous Underwater Vehicle (AUV) minimizes multi-hop data transmission, improving energy efficiency in UASN. However, due to continuous movements, AUV...
Conference Paper
In this article, a new transport protocol named EERT (Energy Efficient Reliable Transport) protocol is proposed for Underwater Acoustic Sensor Network (UASN). EERT is based on Single-Path communication with hybrid features of Forward Error Correction (FEC) and Automatic Repeat request (ARQ). EERT employs the Hadamard code for error detection and co...
Conference Paper
We propose a connectivity-based routing protocol (named CRP) for underwater wireless sensor networks (UWSNs). CRP considers the reliability issue due to high error rate in UWSNs. Hence, during forwarding, a node with the highest connectivity to the sink is selected as a next forwarding node. Using the NS-2 simulator, CRP is compared against a local...

Underwater sensor networks (UWSN) resemble terrestrial sensor networks in many aspects. However, the high propagation delay and limited bandwidth make terrestrial sensor network's protocols unsuitable for UWSN. For instance, routing protocols proposed for terrestrial networks are not applicable in an underwater network. Therefore, enormous efforts...
