The throughput achieved by the traditional routing in cognitive radio sensor network (CRSN) is quite limited because of the instability of wireless links. A spectrum aware based multi-channel opportunistic routing (SAMOR) was proposed, which can overcome the instability of wireless links, and at the same time improve the utilizations of spectrum. When constructing the forwarding candidate set, a modification algorithm was presented which considered the trade-off among the delivery, energy consumption and delay. During the data transmit process, the selection of data channel and relay node is completed in a control channel based cross-layer mechanism (MC-OMAC). Simulation shows that SAMOR perform better than spectrum aware opportunistic routing (SAOR) in average throughput, average loss ratio and average delay. The advantage of SAMOR is more obvious when the average delivery of wireless link is similar.
