As a result of the large area to be monitored in most underwater sensor network applications, many acoustic networks have a sparse topology. The underwater acoustic channel characteristics can cause power consumption of nodes to be quite high. This paper presents information on a work in progre... |

It is well established that path loss in the underwater acoustic channel is dependent on the transmission distance and signal frequency utilized, thereby causing the capacity to be dependent on transmission distance. It has been demonstrated that this dependence of capacity can lead to signific... |

Network monitoring allows network managers to get a better insight in the network traffic transiting in a managed network. In order to make the tasks of a network manager easier, many network monitoring tools are made available for a wide range of purposes (e.g., traffic accounting, performance... |

Network measurement provides vital information on the health of managed networks. The collection of network information can be used for several reasons (e.g., accounting or security) depending on the purpose the collected data will be used for. At the University of Twente (UT), an automatic dec... |
