Awareness networking in wireless environments

This article presented a platform for awareness networking, targeted for distribution of locally relevant control information between nodes in heterogeneous wireless environments. This concept can be leveraged in many different ways and purposes, as shown with the examples given, which range from network discovery, to functionalities required in cognitive radio systems to distributed services facilitating localized mobile social networking. Although a wide range of applications can be envisioned, the same basic solution for distributing locally relevant control information applies to all of them. Future research work on awareness networking is required on multiple areas, covering the technical details of the connectivity solution, details of the distributed algorithms, functionalities, and services, and the regulatory support required for their realization.

ETSI Reconfigurable Radio System - System Aspects and Control Channels for Cognitive Radio

This paper introduces novel results in the area of Cognitive Radio System (CRS) aspects and Control Channels for Cognitive Information Sharing as they are currently elaborated in the framework of the ETSI Reconfigurable Radio Systems (RRS) Technical Body. An overview of the most relevant scenarios for CRS employing opportunistic spectrum usage in the TV White Spaces is given as well as an analysis of inherently required context information provisioning solutions. Finally, an overview on the related regulatory activities and future regulatory challenges are indicated with an emphasis on expected per-device certification mechanisms which will finally enable the introduction of “RadioApps”, i.e. software components provided to Mobile Devices (MD) which will affect the compliance of MDs to the essential requirements of the R&TTE Directive in Europe.
