In traditional automatic retransmission request (ARQ) based wireless broadcasting (WBC) systems, one lost packet is retransmitted per slot to guarantee the correct reception of each packet, which leads to low spectrum efficiency. In this paper, we propose an Ave-Max-Min Network Coding (NC) based WBC protocol. Specifically, to reduce the overall number of retransmissions, lost packets of different...
In cognitive radio (CR) networks, cross-layer design is an important issue since the behavior of one protocol could affect the performance of others. However, for the energy-constraint CR networks, the previous works mostly focus on maximizing the throughput in physical or transport layer, rather than the energy efficiency of the end-to-end transmission control protocol (TCP). In this paper, we propose...
