GPS-free Positioning in Mobile Ad-Hoc Networks

We consider the problem of node positioning in ad hoc networks. We propose a distributed, infrastructure- free positioning algorithm that does not rely on GPS (Global Positioning System). Instead, the algorithm uses the distances between the nodes to build ...

System and method for generating and maintaining a relative positioning system without GPS

Martin Vetterli, Jean-Pierre Hubaux, Srdan Capkun

NOVELTY - At least some of wireless terminals can communicate over wireless links (2) in one or several hops with at least some of the other wireless terminals. The distances (dij) to one-hop neighbors may be measured in a number of the wireless terminals ...

Self-Organization in Mobile Ad-Hoc Networks: the Approach of Terminodes

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Ljubica Blazevic, Levente Buttyan, Srdan Capkun

The Terminodes project is designing a wide area, mobile ad-hoc network, which is meant to be used in a public environment, in our approach, the network is run by users themselves. We give a global description of the building blocks used by the basic operat ...

Detection of fading overlapping multipath components for mobile positioning systems

Ali H. Sayed

The Federal Communications Commission (FCC) mandate for locating the position of wireless 911 callers is fueling research in the area of mobile-positioning technologies. Overlapping multipath propagation is one of the main sources of mobile-positioning err ...

Robust multipath resolving in fading conditions for mobile-positioning systems

Ali H. Sayed

Infrastructure-based mobile-positioning is receiving increasing attention in the field of wireless communications. This is is due to an order issued by the Federal Communications Commission (FCC) that mandates all wireless service providers to locate an em ...

Impact of Time Dissemination Technologies on Synchrophasor Estimation Accuracy

Mario Paolone, Asja Derviskadic, Guglielmo Frigo

The paper discusses the influence of the time synchronization technique on the synchrophasor estimation accuracy in modern Phasor Measurement Units (PMU). Specifically, we make reference to Global Positioning System (GPS), Precision Time Protocol (PTP) and ...
