摘要: In this paper, we present the design of a networked robotic system capable enhancing wireless communication capabilities. The core is active antenna tracking with directional antennas. proposed decentralized and consists mainly mobile robot command center system. Each equipped off-the-shelf network devices such as antennas, access points (AP), switches. For antennas to be beneficial our system, propose weighted centroid algorithm (WCA), which method for direction arrival (DOA) estimation. Through extensive field experiments in different environments selections, omni-to-omni, omni-to-directional, directional-to-directional demonstrate feasibility We expect that can applied variety rescue, surveillance, emergency scenarios where high bandwidth long distance communications are needed.
