Quality of service framework in MANETs using differentiated services

Providing quality of service (QoS) in mobile ad-hoc networks (MANETs) requires a close collaboration between all layers in the protocol stack. To complement other protocols we designed for medium access control, bandwidth sharing and scheduling and QoS routing, we propose here a framework and protocols to support QoS on a per class basis that fit within the differentiated services principle. Our proposed scheme relies on bandwidth provisioning, scheduling and queue qualitative behavior prediction to provide differentiation between two service levels - viz. expedited forwarding and best effort - and cope with mobility MAC layer contingencies.
