Wireless sensors deployed in large agricultural areas can monitor and collect data real time, helping to achieve smart agriculture. But the complexity of environment random deployment method seriously affect coverage quality. The limited capacity sensor batteries greatly limits network lifetime. Therefore, how extend lifetime while ensuring quality is a highly challenging task. This paper proposes node optimization solve problems poor rate short hybrid self-powered networks obstacle environments. first optimizes sensing direction stationary nodes, expands range, repairs holes. Then, an improved bidirectional search A* algorithm used plan avoidance moving path mobile fill remaining holes, improve network. Finally, based on nutcracker optimizer proposed optimal working sequence schedule “sleep or work” state simulation experiment verified effectiveness method, indicating that its performance quality, energy consumption, superior other compared methods.
