Energy-efficient and Secure Communication Data Collection Method for UAV Enabled Wireless Sensor Network
Unmanned Aerial Vehicle(UAV)can serve as a mobile data collection node in secure Wireless Sensor Network(WSN)while extending the lifespan of WSN.However,due to the presence of Eavesdroppers(Eve),the secure communication process between sensors and UAV has been seriously threatened.Therefore,the secure communication party has to consume more resources to ensure the secure performance of communication.A UAV assisted energy-efficient and secure communication data collection method is proposed to address the resource constraints of secure communication in WSN.This method jointly optimizes the trajectory of UAV and scheduling strategies of Sensor Node(SN),minimizing energy consumption of SN while increasing the secrecy capacity of SN.In addition,the method solves complex mixed integer non-convex optimization problem by applying the block coordinate descent technique,and the algorithm jointly solves the trajectory optimization problem of UAV and the scheduling optimization problem of SN by using the continuous convex optimization method.The results obtained from simulation indicate that compared with existing methods,the proposed method has significant advantages in improving energy conservation and secrecy rate.
