Abstract

We propose a new protocol, named DS-SWAN (Differentiated Services-Stateless Wireless Ad Hoc Networks), to support end-to-end QoS in ad hoc networks connected to one fixed DiffServ domain. 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. Furthermore, we present a routing protocol for the ad hoc network, named SD-AODV (Service Differentiation- Ad Hoc On-demand Distance Vector), where new route requests are suppressed to maintain the desired QoS requirements for real-time flows. Simulation results indicate that DS-SWAN and SD-AODV significantly improve end-to-end delays for real-time flows without starvation of background traffic.
