In this paper, we discuss the framework of cognitive radio network, analysis motivations for cross-layer design and security in cognitive radio network (CRN) first. Secondly, we proposed a novel architecture in which the dynamic channel access is achieved by a cross-layer design between the PHY and MAC layers for cognitive radio network. Moreover the resolution of cross-layer security problem is proposed...
In this paper, we discuss the framework of cognitive radio network and OFDMA technology first, and analysis the motivations for cross-layer design in cognitive radio network (CRN). Moreover, we proposed the OFDMA-based cognitive radio transceiver. Finally, a novel architecture in which the dynamic channel allocation is achieved by a cross-layer design between the PHY and MAC layers for OFDMA-based...
With the line rate growing faster and faster, input queued switching architecture has become attractive in high performance switches and routers due to the no speedup character. In this paper, a simple efficient queue balance matching (QBM) algorithm is presented supporting cells with multiple output ports based on the multi-hop routing. The QBM algorithm combines the virtue of iSLIP and EiSLIP, and...
In this paper, we discuss the framework of MCM-Based cognitive radio network (MCM-Based CRN) and motivations for cross-layer design in CRN first. Moreover, we proposed a novel architecture in which the dynamic channel allocation is achieved by a cross-layer design between the PHY and MAC layers for MCM-Based cognitive radio network. Finally, A OFDM-Based cognitive radio transmitter and receiver is...
