Node-Disjoint Multipath Routing and Distributed Cross-Layer QoS Guarantees in Mobile Ad hoc Networks
Xuefei Li, LAURIE G. CUTHBERT · 2006
In this paper, a novel Distributed Cross-Layer QoS (DCLQ) architecture based on node disjoint multipath routing is proposed to provide QoS guarantees for realtime 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 perhop 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.
