Design and implementation of camera network platform for information exchange using dual wireless interface

摘要

Exchange of image information is one of the main features of a camera network. In order to exchange a large amount of information, a platform with good communication speed is needed. In this study, we designed and implemented a specialized camera network platform using Wi-Fi Direct devices. This platform can provide various services to other devices within the same network. We designed the platform in 3 parts: a network, image processing and an embedded database. We modified the operation model of Wi-Fi Direct for adjustment. We designed a method to form a camera network using Wi-Fi Direct. In addition, we proposed two methods for minimizing delay in network formation. The performance of the proposed methods was evaluated using simulation. The feasibility of the proposed platform was also evaluated with experiments. Our results show that the proposed group formation methods outperformed the conventional method.
