Internet of things (IoT), mobile edge computing (MEC),and unmanned aerial vehicle (UAV) have attracted significant attentionin both industry and academic research. By consolidatingthese technologies, IoT can be facilitated with improved connectivity,better data transmission, energy saving, and other advantages. However, the communication between these entities is subject topotential cyber threats. In addition, the integrity of the data mustbe maintained after storing into local storage. Blockchain is a datastructure that supports features like pseudonymity, data integrityetc. This paper represents a blockchain based data acquisition processin which information is gathered from IoTs using UAV as arelay and is securely kept in blockchain at MEC server. In the proposedscheme, data are encrypted prior to transfer to MEC serverwith the assistance of a UAV. Upon receiving the data, MEC servervalidates the data and the identity of the sender. Successful validationis followed by stocking of the data into blockchain, subsequentto obtaining consent from the validators. Security analysisis conducted in order to show the feasibility of the proposed securescheme. Finally, the performance of the proposed scheme is analyzedvia simulation and implementation.
