The invention discloses a load-balance-based satellite network on-demand routing method, which mainly solve the problem of unbalanced traffic load in the conventional satellite network. The load-balance-based satellite network on-demand routing method comprises the following steps that: when a source node sends data, the minimum rectangular region of a routing request is limited according to orientations of the source node and a target node; the source node sends a routing request (RREQ) packet to an intermediate node in the minimum rectangular region; when receiving the RREQ packet for the first time, the intermediate node starts a node load judgment mechanism and selectively forwards the RREQ packet according to a judgment result; when the intermediate node forwards the RREQ packet, theRREQ packet is forwarded to a node with the consistent direction with the target node; the target node replies a routing response (RREP) packet to a route with the minimum load value from the received RREQ packet in a delayed response mode; and after receiving the RREP packet, the source node starts to send data so as to complete the route discovery process. Compared with a method employing the conventional routing protocol, the load-balance-based satellite network on-demand routing method has the advantages that: the accurate traffic load balance of the satellite network can be realized; andthe cost of a network route is reduced.
