In this paper, analysis and delay minimization in CR (cognitive radio) by the router and resource allocation. Firstly cognitive radio was evolve through the software defined radio since 1998 by Joseph mitola. Prior to cognitive radio, SDR was discovered by the Joseph mitola since 1992. A disjoint scheme has compared from joint scheme. Result implemented on mat lab simulation using QAM, it provide high data rate compared to QPSK Modulation. The main focus on minimize the aggregate end to end delay of all the network flows. A distributed solution scheme is developed based on the lagrangian dual problem.
