Trajectory Design for Distributed Estimation in UAV ...
[ ] 11 May 2018 Trajectory Design for Distributed Estimation in UAV Enabled WirelessSensor NetworkCheng Zhan,Member, IEEE,Yong Zeng,Member, IEEE,and Rui Zhang,Fellow, IEEEA bstract In this paper, we study an unmanned aerial ve-hicle (UAV)-enabled wireless sensor network, where a UAV isdispatched to collect the sensed data from Distributed sensornodes (SNs) for estimating an unknown parameter. It is revealedthat in order to minimize the mean square error (MSE) for theestimation, the UAV should collect the data from as many SNs aspossible, based on which an optimization problem is formulatedto Design the UAV s Trajectory subject to its practical mobilityconstraints. Although the problem is non-convex and NP-hard, weshow that the optimal UAV Trajectory consists of connected linesegments only. With this simplification, an efficient suboptimalsolution is proposed by leveraging the classic traveling sales-man problem (TSP) method and applying convex optimizationtechniques.
