Abstract: Multi-path routing protocols in wireless mobile Ad hoc networks have drawn researchers’ attention due to its good performance.However，the protocols maintain condition of“shortest path” with minimum hops measurement.Research shows that the path with minimum hops may not provide the minimum end-to-end delay guarantee.This paper proposes a new multi-path routing protocol in consideration of end-to-end delay，i.e. QAOMDV.The protocol，based on a cross-layer design method，introduces a new metric“shortest queue”.The simulation results demonstrate that QAOMDV performs much better，in terms of end-to-end delay，packet delivery ratio and so on.
