Research in Software Defined Networks (SDN) has gained momentum in recent years. SDNs are getting mature, however, there are still many research challenges that need to be considered before SDN become ubiquitous. The adaptation of the technology brings immediate focus to its security aspects. The centralized nature of the SDN makes it prone to many...

Electromagnetic (EM) waves used to send signals under seawater are normally restricted to low frequencies () because of sudden exponential increases of attenuation () at higher . The mathematics of EM wave propagation in seawater demonstrate dependence on relative permeability (), relative permittivity (), conductivity (), and of transmission. Esti...

In this research paper, we estimated absorption loss (Lα) and spreading loss (Lo) based on electromagnetic (EM) waves propagation, considering multiple seawater depth (1101) points from surface to 5500 m distributed uniformly with 5‐m difference. Estimation of parameters aforementioned was done based on world ocean data (WOD13) from the National Ce...

Interest in underwater wireless sensor networks (UWSNs) based on acoustic communication has rapidly grown over the last decade. In this field, the design of energy-efficient communication protocols is a crucial task as battery replacement may be unfeasible in practical scenarios. While routing protocols play a pivotal role in determining the effici...
Thesis
Full-text available
In Underwater Wireless Sensor Networks (UWSNs), the major challenges are high propagation latency in data transmission, dynamic topology of nodes due to wave movements and high power consumption of acoustic modem. Depth based routing as a subcategory of localization-free routing protocols, is designed to cope with the above mentioned challenges. In...

In the last decade, underwater wireless sensor networks (UWSNs) have attracted a lot of attention from the research community thanks to their wide range of applications that include seabed mining, military and environmental monitoring. With respect to terrestrial networks, UWSNs pose new research challenges such as the three-dimensional node deploy...
Chapter
Full-text available
In the last decade, Underwater Wireless Sensor Networks (UWSNs) have been widely studied because of their peculiar aspects that distinguish them from common wireless terrestrial networks. In fact, most UWSNs use acoustic instead of radio-frequency based communications, and nodes are subject to high mobility caused by water currents. As a consequenc...
Preprint
In Underwater Wireless Sensor Networks (UWSNs), traditional enhancements of Depth-Based Routing (DBR) scheme rely either on increasing the network overhead or on the adoption of offline localization schemes to improve the network performance in terms of energy consumption, end-to-end delay or network throughput. Unfortunately, localization based te...

In this paper, we present Dynamic Sink Mobility equipped DBR (DSM) routing protocol for Underwater Wireless Sensor Networks (UWSNs). Our proposed scheme increases the stability period, network lifetime, and throughput of the UWSN. The scheme incorporates dynamic sink mobility in a way that sink moves towards most dense (in terms of number of nodes)...
Conference Paper
Cooperative routing is a hybrid approach utilizing routing techniques and cooperative communication to improve the communication quality of single-antenna sensor nodes. It exploits the broadcast nature of wireless medium and transmits cooperatively using nearby sensor nodes as relays. In this research, a cooperative transmission scheme is proposed...

Appropriate network design is very significant for Underwater Wireless Sensor Networks (UWSNs). Application-oriented UWSNs are planned to achieve certain objectives. Therefore, there is always a demand for efficient data routing schemes, which can fulfill certain requirements of application-oriented UWSNs. These networks can be of any shape, i.e.,...

We propose forwarding-function (íµí°¹ íµí°¹) based routing protocol for underwater sensor networks (UWSNs): improved adaptive mobility of courier nodes in threshold-optimized depth-based-routing (iAMCTD). Unlike existing depth-based acoustic protocols, the proposed protocol exploits network density for time-critical applications. In order to tackle...

Depth-based routing protocols play a key role in assuming realistic approach by considering the continuous node movement in aqueous environment. The performance attributes of depth-based routing protocols highly depend upon the depth information of sensor nodes. Although this information is not prioritized by all acoustic models to estimate channel...
