In this paper, a novel Distributed Cross-Layer QoS (DCLQ) architecture based on node disjoint multipath routing is proposed to provide QoS for real-time traffic and best-effort traffic in mobile ad hoc networks. Without any extra control overhead, DCLQ can schedule packets of real-time flows according to their per-hop QoS requirements. DCLQ implements per-hop delay QoS aware priority scheduling and QoS consideration of MAC layer to ensure that real-time flows and best-effort flows can achieve their desired service level.
