An interaction model between ad-hoc networks and fixed IP networks for QoS support
Mari Carmen Domingo, David Remondo · 2004
We propose a new protocol, named DS-SWAN (Differentiated Services-Stateless Wireless Ad Hoc Networks), to support end-to-end QoS (Quality of Service) in ad hoc networks connected to fixed DiffServ domains. DS-SWAN warns nodes in the ad hoc network when congestion is excessive for the correct functioning of real-time applications. These nodes react by slowing down best-effort traffic. Simulation results indicate that DS-SWAN significantly improves end-to-end delays for real-time flows without starvation of background traffic. In this work we introduce different conditions to force that a wireless node throttles its best-effort traffic and study their behaviour and differences.
