Joint power-subcarrier-time resource allocation is imperative for wireless mesh networks due to the necessity of packet scheduling for quality-of-service (QoS) provisioning, multi-channel communications, and opportunistic power allocation. In this work, we propose an efficient intra-cluster packet-level resource allocation approach. Our approach takes power allocation, subcarrier allocation, packet...
In this paper, we investigate a cross-layer design for the packet scheduling and the resource allocation in UWB systems. This design considers the combination of queuing and channel state information (CSI) which provides QoS support for multimedia applications in UWB. For the physical layer, the use of a linear precoded orthogonal division multiplexing (LP-OFDM) waveform is proposed because of its...
We consider a channel aware scheduling for the downlink multi-service flows in orthogonal frequency division multiple access (OFDMA) based mobile WiMAX (Worldwide Interoperability for Microwave Access)system. We propose an intelligent medium access control (MAC) that adapts with the physical layer in response to the different QoS requirements of the diverse service flows in the system. This adaptation...
