TL;DR: EvalVid is targeted for researchers who want to evaluate their network designs or setups in terms of user perceived video quality, and has a modular construction, making it possible to exchange both the network and the codec.

TL;DR: Key issues coming up in wireless fieldbus and wireless industrial communication systems are discussed: fundamental problems like achieving timely and reliable transmission despite channel errors; the usage of existing wireless technologies for this specific field of applications; and the creation of hybrid systems in which wireless stations are incorporated into existing wired systems.

TL;DR: A vision of a Cognitive Radio (CR) based approach that uses allocated spectrum in a opportunistic manner to create "virtual unlicensed bands" i.e. bands that are shared with the primary (often licensed) users on a non-interfering basis is presented.

TL;DR: The authors present results of bit error measurements taken with an IEEE 802.11-compliant radio modem in an industrial environment and show that the popular Gilbert/Elliot model and a modified version of it are a useful tool for simulating bit errors on a wireless link, despite their simplicity and failure to match certain measured statistics.

TL;DR: Two algorithms for dynamically adjusting transmission power level on a per-node basis are proposed and it is shown that these local algorithms outperform fixed power level assignment and that the lifetime achieved by them is usually within a factor of two of globally computed solution while being scalable.
