Abstract

In this work, we study data collection in unmanned aerial vehicle (UAV) aided mobile wireless sensor networks (WSNs). The network topology is changing under the mobility of the UAV and the sensor nodes, the design of efficient data collection protocols is a major concern. We address such high dynamic network and propose a prioritized-based collision-free data collection algorithm, called PCdFS algorithm, which is highly efficient. Two key design ideas for PCdFS are: (a) no need of higher priority for those nodes that have lower transmission rate between them and the UAV and (b) improve the communication opportunity for those nodes that have shorter contact duration with the UAV. We demonstrate the performance of PCdFS algorithm through extensive simulations, and real experiments. These experiments using 15 mobile nodes at a path with 10 intersections and 1 island, presents that the network fairness is efficiently enhanced. We also confirm the applicability of PCdFS algorithm in a challenging and realistic scenario through numerous experiments on a path in Tongji campus in Shanghai, China.
