Due to dynamic and diversity of spectrum for cognitive radio networks,traditional routing algorithms can't be completely suitable for it.In this paper,research status on cross-layer design of dynamic spectrum allocation and routing are analyzed and summarized.In order to avoid the effect for network performance from crossing node,weighted hop count and link state work as the route standard,minimum cumulative interference is utilized as the channel assignment standard.Graph coloring model is taken as route analysis model,an improved algorithm of channel assignment and path selection(ICARS) are proposed for hybrid cognitive radio networks in this paper.Simulation results show that the ICARS algorithm can obtain better network communication quality.It can provide an effective method for routing design of hybrid cognitive radio networks.
