Abstract: A routing protocol LC-OLSR of cognitive links is proposed based on OLSR routing protocol. The protocol detects and analynizes the node load, link delivery ratio, and link availability, and collects the quality evaluation of path links among the nodes on the network to achieve the selection of routing, enhance the throughput of the network, and improve the load balance. The simulation results show that LC-OLSR can improve the packet delivery rate of wireless Mesh networks and reduce the average end-to-end delay.
