Drone Placement Considering Connectivity in Cable-Length-Constrained Wired Drone Networks

Wired drone networks have emerged as an alternative to wireless multi-drone systems by eliminating radio interference and enabling stable data transmission. In such networks, drone placement must jointly consider sensor coverage and network connectivity under cable-length constraints caused by drone payload limits. In this paper, we propose a connectivity-aware drone placement method for cable-length-constrained wired drone networks. We formulate the placement problem to maximize the number of relayed sensors while satisfying perdrone cable-length constraints and ensuring full connectivity. The proposed method combines a greedy-based initial placement strategy with a connectivity-aware neighborhood search. Through simulation experiments, we show that our proposed method efficiently finds feasible solutions and achieves higher sensor coverage than simulated annealing method.
