Depending on whether bidirectional links or unidirectional links are used for communications, the network topology under a given range assignment is either an undirected graph referred to as the bidirectional topology, or a directed graph referred to as the unidirectional topology. The Min-Power Bidirectional (resp., Unidirectional) k-Node Connectivity problem seeks a range assignment of minimu...

In this paper we explore the limits of the unidirectional pulse propagation equation (UPPE) in general nonlinear media. Our main aim is to investigate under which physical conditions two-way propagation becomes significant, and leads to a breakdown of the unidirectional approximation. Using a spectral constraint appearing in the derivation of UPPE we derive a first correction which renormalizes...

A unidirectional link exists in an ad-hoc network when a node B is within the transmission range of another node A while node A cannot directly hear node B. However, a reverse route from B to A might exist, by going through multiple nodes. Unidirectional links may exist in an ad hoc network due to variation in transmission power of different nodes, noise or other signal propagation phenomena, a...

Anderson, James Robert M.S.E.E., Purdue University, May, 1997. Multidimensional Network Performance. Major Professor: Seth Abraham. The interconnection network in a parallel processing system can have a profound impact on the success of a system in terms of performance or cost. The ability to clearly determine the trade-offs between performance and cost during the design of a network is critica...

Dynamical control of biological systems is often restricted by the practical constraint of unidirectional parameter perturbations. We show that such a restriction introduces surprising complexity to the stability of one-dimensional map systems and can actually improve controllability. We present experimental cardiac control results that support these analyses. Finally, we develop new control al...

This document describes a set of Extension Headers for the Unidirectional Lightweight Encapsulation (ULE), RFC 4326. The Extension Header formats specified in this document define extensions appropriate to both ULE and the Generic Stream Encapsulation (GSE) for the second-generation framing structure defined by the Digital Video Broadcasting (DVB) family of specifications.
