Dynamic spectrum sharing technology through the underlay approach in cognitive radio systems is becoming one of the most important issues to improve the spectrum utilization. In this paper, we first introduce a novel routing selection scenario for underlay spectrum sharing network. The scenario consists of three parts: spectrum management network (SMN), secondary user network (SUN) and primary user network (PUN). Through the spectrum information collection in SMN and the spectrum related information exchange between the SMN and SUN in a common channel, the underlay model can avoid the interference to the PUN as much as possible. To better establish an effective and practical routing selection model in SUN and minimize the interference to PUN, we propose a self-awareness routing (SAR) scheme, based on the power control approach and the router capacity metric. The simulation results validate that SAR can achieve a high level performance not only in the routing quality, but also in the minimization of the interference to the PUN.
