The overall performance of multi-hop cognitive radio networks (CRNs) can be improved significantly by deploying the channel diversity of orthogonal licensed channels in spectrum underlay fashion. However, interference due to the sharing of common radio channels among links and congestion due to the contention among those flows that share the same link become an obstacle to meet this challenge.

Recently, telecommunications network is considered to be evolving to the Next Generation Network(NGN) which capable of converging heterogeneous networks and provides converged services. The leading telecommunication operators have already tried to construct an NGN. It is one of the trends that DiffServ-aware MPLS is adopted as an NGN core network technology. Resource and Admission Control Function(RACF)...
