Abstract ：Wireless sensor network is an important technique that is used in industry and agriculture as a monitoring network.In ， ， large-scale monitoring applying condition wireless sensor network has the characteristics of ultra-large-scale ultra-low-cost and complex topological changing which results in its limited transmission.It brings the network protocol rigorous requirements.The ex－ ， ， ， ’ ， ’ isting protocol algorithms such as CNS SPT and GIT don t consider these characteristics roundly so they can t be applied di－ （ ） ， rectly.An equally effective routing algorithm based on fine-grain gradient FGLRA is proposed.Furthermore based on routing theo－
