The invention discloses a hybrid wireless sensor network routing method based on gradient, a sensor node, the sink sink fixed and mobile wireless network, a sensor node based on the hop gradient with fixed sink node; mobile sink node and sensor nodes in the neighbor maintenance; the mobile sink node in the mobile radio tag HELLO package; combined with the gradient information of fixed node and mobile sink, mobile sink, a local data reporting path for mobile sink, and the three level path dynamic refresh, you can directly enter the data forwarding. The invention establishes an optimized data reporting path between the sensor node and the sink node, and fully utilizes the mobility of the mobile sink, optimizes the network performance, and effectively suppresses the protocol overhead in the path establishment process.
