The radio resource shortage is one of the most important problems to be considered when deploying modern wireless telecommunication systems. A novel communication paradigm named cognitive radio, has been introduced in the last years for a more efficient exploitation of the limited available spectrum. Its main aim is to allow the co-existence of different wireless systems on the same spectral resources by limiting the mutual interference. In this paper we consider a cognitive approach environment where the primary system is an OFDMA network. In this paper a MAC protocol based on the Wireless Token Ring approach is proposed for a secondary network aiming to exploit the OFDMA framing structure of the primary network.

Abstract
The radio resource shortage is one of the most important problems to be considered when deploying modern wireless telecommunication systems. A novel communication paradigm named cognitive radio, has been introduced in the last years for a more efficient exploitation of the limited available spectrum. Its main aim is to allow the co-existence of different wireless systems on the same spectral resources by limiting the mutual interference. In this paper we consider a cognitive approach environment where the primary system is an OFDMA network. In this paper a MAC protocol based on the Wireless Token Ring approach is proposed for a secondary network aiming to exploit the OFDMA framing structure of the primary network.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
