OSPF protocol routing metric improvement method for wireless ad hoc network

The invention discloses an OSPF (Open Shortest Path First) protocol routing metric improvement method for a wireless ad hoc network. The method comprises the following steps: S1, operating an OSPF protocol; and starting routing protocol software, running an OSPF protocol and configuring a router and an interface. S2, resetting an interface type; and the type of the interface connected to the wireless broadcast link is reset to be the type of the Point-to-MultiPoint interface. S3, link quality detection; and the router sends a link detection message to the neighbor router to detect the link quality. S4, setting link quality; and the router is used for respectively setting the link quality for the neighbor routers which can be reached by the Point-to-MultiPoint interface. And S5, carrying out routing calculation. And the router carries out shortest path calculation according to the new link quality. The method can be used for applying the OSPF protocol in the wireless ad hoc network, and is used for optimizing
