Abstract

In forest and crop monitoring operations, crop environmental information can be collected by self-organizing WSN formed by spreading wireless sensor nodes. When the UAV is applied to the clustered WSN as the mobile sink node for data collection, the UAV needs to forward not only the information of each cluster head node, but also the important information detected by its own sensor. In order to ensure the timely forwarding of UAV sensor detection information, further reduce the energy consumption of cluster head node and prolong the life of WSN network, this paper proposed an asynchronous data forwarding polling control system with priority, and used Markov chain and probability generating function to model and analyze the system performance. Using FPGA with asynchronous reading and writing FIFO function as the main control device, it designed the hardware circuit structure of the polling system based on FPGA, which verified the feasibility and high efficiency of the polling control system. Experimental results show that the proposed scheme can ensure timely transmission of important data by UAV, shorten service delay, improve WSN energy efficiency and optimize system performance.
