A multi-route routing method based on network coding in wireless network includes the following steps: 1) routing discovering from originating nodes to object nodes; 2) after the routing discovering stage is finished, comparing route conversion incomes of each route, and originating nodes selecting the optimum W routes therein for data transmission. Compared with the prior technology, the invention proposes a multi-route routing method based on network coding in wireless network, dynamically transmits data packets on multiple routes according to reliability and coding opportunity of routes, dynamically creates rather than only waiting for coding opportunity through conversion transmission path, and multiple routes share network flow quantity loads, and maximize the route conversion, accordingly improving network output.
