Abstract :
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.
