Much effort and ingenuity has been applied to develop tomographic methods to derive link-
level performance statistics (packet delay and loss rates) from end-to-end measurements …

Due to its many advantages the wavelet transform has become in the last decade a very
popular numerical tool for general purpose signal analysis and processing. It belongs to the …

In this paper, a network tomography (NT) approach is proposed to study network
performance in ad-hoc networks. An analysis of network performance is presented in a …

Owing to the inherent characteristic of Ad Hoc network, a multi-hops, self-organized wireless
network, it is difficult to adopt traditional measurement technique in Ad Hoc network. Based …

Network tomography is a problem of estimating network properties such as the packet loss
rates of links using available packets. There are two kinds of methods to measure packets …

Internet traffic primarily consists of packets from elastic flows, ie, Web transfers, file transfers
(FTP), and e-mail, whose transfers are mediated via the transmission control protocol. We …

The performance analysis of the mobile ad-hoc network (MANET) is a challenging issue. In
this paper, network tomography is studied to analyse the network performance in a dynamic …

We study the problem of learning a latent tree graphical model where samples are available
only from a subset of variables. We propose two consistent and computationally efficient …

The Internet has become a key medium through which citizens around the globe
communicate, collect information, and express their opinions. Over the past few decades …
