DSR-Based Cross-Layer QoS Design in Ad Hoc Networks
Keming Du, Yilin Chang, Bin Li · 2010
Because of limited bandwidth and dynamic topology, it is difficult to provide QoS(Quality of Service) guarantee in ad hoc networks. The aim of the paper is to utilize the wireless resources efficiently and to meet QoS requirements of multimedia applications in ad hoc networks. Here, the model of Policy-based Cross-layer QoS design for Ad hoc Networks is introduced. Then a cross-layer routing protocol with QoS guarantee for Ad hoc networks, QBDSR (QoS-Based DSR), which is based on DSR routing protocol, is proposed and its performance is analyzed. The simulation results show that the QBDSR routing protocols are able to meet QoS requirements of voice, video and other multimedia services.
