Given that applications and services for evolving mobile ad hoc networks (MANETs) have diverse quality of service requirements in a similar fashion to fixed networks, this paper proposes a proportional service differentiation (PSD) model. This model is highly scalable and simple to adopt in MANETs because it does not require explicit admission control or maintenance of state information in any intermediate node. It relies instead on localized scheduling and buffer management to achieve a

This association is performed with a view to improve end-to-end service differentiation, although no other explicit mechanisms are used to achieve end-to-end guarantees. This model takes also into consideration the time-varying nature of available bandwidth in MANETs, and tries to calculate it dynamically. Simulation results confirm the per-hop performance improvement.
