On Ad Hoc Communication in Industrial Environments

High-Precision Ad-Hoc Indoor Positioning in Challenging Industrial Environments

This paper addresses the problem of providing high-precision positioning in industrial environments. Such environments are extremely challenging due to the adverse effects of multipath fading caused by the abundance of metallic objects, the physical layout of the environment which is often complex, and the lack of fixed positioning system infrastructure. Several technologies are assessed with r...

Fine Synchronization in UWB Ad-Hoc Environments

UWB impulse radios (UWB-IR) have attracted increasing interest due to their potential to propose high user capacity with low-complexity and low-power transceivers (Win & Sholtz, 2000). It is approved by the Federal Communications Commission’s (FCC) Report in which the UWB spectral mask is released and published in February 2002. Most of these benefits initiate from the distinctive characteristi...

Mobility-based communication in ad hoc networks

We introduce the concept of mobility-based communication in ad hoc networks, meaning that the packet transport is performed mainly by the nodes’ movement. We outline a model for such networks, utilizing a stochastic model for the geographical location of the nodes. A test case is defined in which three strategies for packet forwarding are presented and evaluated.
