This paper presents the application of a matrix based technique to eliminate the assumption of a known routing matrix in network tomography. Network tomography is an effective means of determining network performance parameters such as delay and packet loss rate (PLR). It gives indirect inference of network characteristics using active probes or passive monitoring of packets. Most of the network tomography...
We introduce a novel concept of multiple metric network tomography in this paper. The conventional network tomography observes a single parameter directly and infers another parameter indirectly from the the directly measured parameter. We consider observing two parameters (packet loss rate (PLR) and path delays) directly and use both of these parameters to infer a single parameter indirectly. We...
To maximize the potential of three-dimensional integrated circuit architectures, 3D CAD tools must be developed that are on-par with their 2D counterparts. In this paper, we present a statistical static timing analysis (SSTA) engine designed to deal with both the uncorrelated and correlated variations in 3D FPGAs. We consider the effects of intra-die and inter-die variation. Using the 3D physical...
Group testing has been used in many applications to efficiently identify rare events in a large population. In this paper, the concept of group testing is generalized to applications with correlated source models to derive scheduling policies for sensors' adopting cooperative transmissions. The tenet of our work is that in a wireless sensor network it is advantageous to allocate the same channel dimensions...
In this work we investigate the effects of multiple access interference (MAI) and polarization mode dispersion (PMD) in optical code division multiplexing (OCDM) lightpaths. These paths are determined by the data encoding with non-coherent optical orthogonal codes (OOC), using a sequence inversion keying (SIK) optical correlator system. Our results show the impact of MAI effects and PMD constraint...
