The invention provides a method for designing a multi-channel opportunistic routing protocol (MCORP) in a cognitive radio sensing network (CRSN). In the method, the priority orders of competitive nodes of each node are determined by weighing the residual electricity amount of the competitive nodes, and delivery ratio and ETX between the node and the competitive nodes thereof. The delivery ratio and the ETX of each link are obtained by calculating the average value of all channels in the network. Energy consumption is increased while a competitive node set is enlarged. In view of the finiteness of the energy of nodes, weighing is required to be considered between the delivery ratio and the energy when the value of the competitive node set is selected in order to decrease energy expenditure. For this purpose, the invention provides an evaluation index EDP (expected energy delivery ratio per joule) in order to weigh the relation of the delivery ratio and the energy. A simulation result further proves that the routing protocol provided in the invention has better performance than a multi-channel routing protocol (MCR) in aspects of throughput and data packet loss rate.
