QoS-aware routing schemes are important for real-time applications like VoIP. The authors proposed the delay-aware routing method with use of multiple routing tables to reduce end-to-end delay of real-time communications. This method set routing paths by setting real-time applications and non-real-time applications separately. This method uses two routing tables calculated by minimum spanning tree taking into account link costs and node numbers. Therefore, the number of the routing hops can be decreased. However, the calculated tables are dependent on node numbers. The proposed method improves routing tables, with use of node centricity. Simulation results show that the number of the hops is reduced compared with the former method and end-to-end delay is reduced. Also, compared with the former method, the results show that the proposed methods enable the keeping of throughput.
