COST action IC0902 "Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks"

One of the fundamental tasks of a wireless device with cognitive radio functionalities is to extract relevant parameters from other wireless networks in range, through the so called spectrum sensing. This function is a key element in a cognitive radio system as it should be firstly performed before allowing unlicensed users to access a vacant licensed channel. Among other well know techniques already used to detect communicating primary users, the most simple and effective is based on energy detection.
This work is part of a project called AIRAWARE that aims at the definition of a software module able to classify a set of different wireless technologies in the ISM band thanks to an energy detector based algorithm.

It has been presented during the 1st Workshop of COST Action IC0902, Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks, on November 23–25, 2010, in Bologna. Mateterials about the Bologna workshop are available here .

Cos'è SerendipiTAG

SerendipiTAG è un sistema di supporto al processo di ricerca delle informazioni, sviluppato all'interno del CSP e basato sull'uso di tag.
Il sistema, sulla base dei tag utilizzati all'interno dei tre strumenti di comunicazione del CSP (sito web, web tv e blog) suggerisce percorsi di ricerca alternativi in grado di aumentare le probabilità di successo e al contempo supportare i processi di serendipità: la possibilità cioè di trovare risultati coerenti con la ricerca effettuata, seppur in direzioni inaspettate.
Alla ricerca della voce "regione piemonte”, per esempio, è possibile trovare anche risultati alternativi attraverso il suggerimento di altre parole correlate quali banda larga, innovazione, PMI.

What is SerendipiTAG

SerendipiTAG is a tag-based recommendation web environment designed to support users when searching for information.
Based on the tags of the three sections of CSP website (website, blog and webTV) cthe system offers alternative search paths which increase the likelihood of a successful search and at the same time support processes of serendipity: the probability of finding results that correspond to the search in question, albeit in unexpected directions. A search for the term “content management system”, for example, also yields alternative results regarding additional related keywords, such as Joomla, Drupal and Wordpress, three well-known CMS.
