Quality of service routing without global information exchange

We propose a novel localized QoS routing approach, under which no global QoS state information exchange among network nodes is needed. This approach has many advantages over the conventional global QoS routing approach based on information exchange among routers. We develop two localized QoS routing schemes and demonstrate through simulations that the proposed localized QoS routing approach is indeed a viable alternative to the global QoS routing approach.
