Unmanned aerial vehicle (UAV)-assisted wireless sensor network (WSN) data transmission is a hot topic of research in recent years. This article mainly focuses on the energy consumption optimization of WSN data transmission with the assistance of UAVs. First, we established a communication coverage model for UAV-WSN and derived the energy consumption of data transmission for UAV-WSN, determining the optimal number of cluster heads (CHs) under different UAV flight heights. Second, we built a model for the energy consumption of WSN data transmission and the UAV flight height, and determined the optimal flight height of the UAV, while also dividing the UAV task area into segments. Then, we proposed a model that dynamically optimized the UAV data collection position according to the CH location, which can further reduce the energy consumption of CHs during data transmission. Finally, we used simulation experiments to verify the feasibility and effectiveness of our proposed scheme.

“…In each iteration, the node with highest weight will be selected as the rendezvous point, and weights of nodes should be updated. The authors in [22] designed multilevel routing framework with dynamic spanning tree to balance the network load and prolong the network lifetime, where some nodes are selected as the rendezvous points based on the motion of mobile sink.…”

Recent studies have demonstrated the advantage of applying mobile sink to prevent the energy-hole problem and prolong network lifetime in wireless sensor network. However, most researches treat the touring length constraint simply as the termination indicator of rendezvous point selection, which leads to a suboptimal solution. In this paper, we notice that the optimal set of rendezvous points is unknown but deterministic and propose to elect the set of rendezvous points directly with the multiwinner voting-based method instead of step-by-step selection. A weighted heuristic voter generation method is introduced to choose the representative voters, and a scoring rule is also well designed to obtain a satisfying solution. We also employ an iterative schema for the voting score update to refine the solution. We have conducted extensive experiments, and the results show that the proposed method can effectively prolong the network lifetime and achieve the competitive performance with other SOTA methods. Compared to the methods based on step-by-step selection, the proposed method increases the network lifetime by 23.2% and 10.5% on average under the balanced-distribution and unbalanced-distribution scenarios, respectively.
