Abstract: In order to solve the resource distribution problem in the joint resource allocation model，a novel power control and channel assignment algorithm is proposed，which is named CCJPCA ( Congestion Control oriented Joint Power control and Channel assignment Algorithm) ． In the CCJPCA algorithm，the hybrid coding
strategy is used to achieve the co-evolution of the power and channel variable． The reward mechanism of Q-Learning algorithm is used to realize the adaptive selection of mutation strategy，which ensures the reasonable allocation of network resource． The simulation results based on NS-3 ( Network Simulator-3 ) indicate that CCJPCA algorithm can give priority to network resources of network bottleneck links， achieve algorithm convergence speed，reduce network queuing and retransmission delay，and lower the average packet loss ratio．
