Delay estimation in a two-node acyclic network.
Linear measures such as cross-correlation have been used successfully to determine time delays from the given processes. Such an analysis often precedes identifying possible causal relationships between the observed processes. The present study investigates the impact of a positively correlated driver whose correlation function decreases monotonically with lag on the delay estimation in a two-n...
متن کاملNeural-Network-Based Time-Delay Estimation
A novel approach for estimating constant time delay through the use of neural networks (NN) is introduced. A desired reference signal and a delayed, damped, and noisy replica of it are both filtered by a fourth-order digital infinite impulse response (IIR) filter. The filtered signals are normalized with respect to the highest values they achieve and then applied as input for an NN system. The ...
متن کاملScalable, Low-Overhead Network Delay Estimation
Estimating the network delays between each pair of nodes in a multicast session is the key parameter in reliable multicast; it is used, among other things, in suppressing the implosion of request and repair packets, and in detecting congestion. Existing implementations useO(n) multicasts withO(n) message size each (total of O(n) bits); here, n is the session size. We present a new protocol that...
متن کاملNetwork tomography for internal delay estimation
On-line, spatially localized information about internal network performance can greatly assist dynamic routing algorithms and traffic transmission protocols. However, it is impractical to measure network traffic at all points in the network. A promising alternative is to measure only at the edge of the network and infer internal behavior from these measurements. In this paper we concentrate on ...
متن کاملNode Delay
Different deployments of mobile ad hoc networks (MANETs) can have widely varying characteristics that greatly impact the behavior of different routing protocols created for these networks. Before applications can be deployed in such environments, it is important for developers to understand the potential quantitative behavior of the protocols that support their applications. Analytical models e...
