(A) control integrated query processing system for controllable mobile wireless sensor networks

Abstract

With the recent development of controllable mobile nodes such as Unmanned Aerial Vehicles (UAVs),it became possible to collect information remotely from target areas, and attempts has been made to collect accurate data from a wider range through cooperation of multiple nodes. However, previous systems are less automated in the way that human intervention is still required to execute missions, and they were implemented for the only purpose of carrying out specific scenarios. In order to solve those problems, we propose a control integrated query processing system. A high-level language that integrates node control and data collection queries enables users to conveniently express various tasks and according to the contents of the query, the nodes automatically perform their tasks without human intervention. In addition, the system intervenes directly in the movement of each node in the query execution process and performs the role of preserving the network connection between the mobile nodes. In this paper, we describe the structure and operation of the system, present the operation results of the query language through the implementation of the test bed using real UAVs, and evaluate the network maintenance performance through our simulator.
