We propose a novel auto repeat request (ARQ) protocol with cross layer design, in order to guarantee quality-of-service (QoS) for wireless multi-hop network. With the cross layer design, the ARQ mechanism has the promise to meet different QoS requirements and adapt to various channel conditions. With the self-configure mechanism of the mode of end to end or hop by hop ARQ, the novel ARQ protocol can meet the time delay need of different service. The theory analysis and simulation results show that the proposed mechanism can improve user experience of various services under heavy burden transmission condition, and improve the network performance significantly.
Keywords:Auto repeat request; Cross layer design; Multi-hop; QoS cognitive network
