Advances in low-power electronics design and wireless communication have enabled the development of low cost, low power micro-sensor nodes. These sensor nodes are capable of sensing, processing and forwarding which have many applications such as underwater networks. In underwater wireless sensor networks (UWSNs) applications, sensors which are placed in underwater environments and predicted ena...

underwater acoustic wireless sensor network (uawsn) use acoustic signalsto transmit data. acoustic signals in underwater environment have high bit errorrate, long propagation delay and limited bandwidth. another constraint in uwasnis energy. due to these constraints, design of energy and bandwidth efficient andpropagation delay aware mac protocol is a great challenge in uwasn.underwater sensor ...

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...

recently, data collection from seabed by means of underwater wireless sensor networks (uwsn) has attracted considerable attention. autonomous underwater vehicles (auvs) are increasingly used as uwsns in underwater missions. events and environmental parameters in underwater regions have a stochastic nature. the target area must be covered by sensors to observe and report events. a ‘topology cont...

In recent years underwater wireless sensor networks (UWSNs) have emerged as one of the most popular researched areas in the networking field due to its numerous applications in ocean exploration, underwater surveillance and pollution detection. With specific characteristics such as higher delay in transmission, continuously moving nodes, limited storage and battery, most of the routing protocol...

In this paper, we propose a cluster-based synchronization algorithm for underwater acoustic sensor networks based on MU-Sync, called EMU-Sync. Time synchronization is an important part of many services. Although many time synchronization protocols for terrestrial wireless sensor networks have been well-developed, none of them can be applied directly in underwater wireless sensor networks. The c...

Localization of mobile sensor nodes is indispensable for underwater sensor networks. For example, in aquatic environment monitoring applications, localization is a must-do task in order to get useful location-aware data. Location information is also required for geo-routing, which is proved to be more scalable and efficient in mobile underwater sensor networks. So far, only a limited number of ...

A lot of researchers lately have attained the attention of Wireless Sensor Networks. On the other hand, when measures it up to the terrestrial or global WSN, Underwater Sensor Networks (UWSN) depicts an innovative networking standard. The exploitation of Underwater Sensor Networks is not simple or clear-cut, fundamental defies are therefore required to be mapped just because the sort of setting...

Underwater Wireless Sensor Networks (UWSNs) provide a new opportunities to examine and predict the activities of aquatic environments. Some applications such as target tracking , disaster prevention etc where sensed data is worthless without any location information. Localization is the process of estimating the location of each node in a sensor network. In underwater sensor networks (UWSNs) de...
