A method and apparatus is provided for using a distributed multi-path QoS-aware routing scheme that considers basic MANET characteristics to meet transport service requirements of real-time applications and makes use of multiple discovered paths to calculate a next-hop decision. The QoS Routing scheme superimposes distributed neighborhood congestion, neighborhood density, and link stability and delay information over the multiple discovered paths when the next-hop decision is calculated.

Integrating local congestion and path interference into QoS routing for wireless mobile AD HOC networks

This paper proposes adaptation of Mobile Ad-hoc Network (MANET) [13] routing protocols taking stability of links as primary consideration. The presented scheme can be associated with a resource reservation strategy to ensure Quality Of Service (QoS). Packets routed through stable routes have very low waiting time in queue which reduces end to end delay. The overall performance shows that the developed adaptation can support a higher degree of QoS as compared to the conventional version of MANET routing protocol.
