Smartphone Camera-Based Optical Wireless Communication System: Requirements and Implementation Challenges

Implementation of a Wireless Communication Technologies based Home Security System

Recently, the demand for home security in the world is intensifying due to the aging population with low birth rate and the significant increase in number of nuclear family with dual working parents. Some enterprises like SECOM, ALSOK, CSP, provide home security services in Japan and many other places. However, most of these services rely on security guards, which is expensive. Besides, some fa...

Optimization of an Optical Wireless Communication System

This paper presents a preliminary study aimed to optimize the signal characteristics of an optical indoor wireless communication system for telemedicine and mobile user applications. Specifically, detected signals associated with experimental geometries based on line-of-sight (LOS)-pointto-point-optical link and line-of-sight (LOS)-point-to-pointparallel to a surface-optical links are shown. In...

Marine based Wireless Sensor Networks: Challenges and Requirements

Marine environmental monitoring based on wireless sensor networks (WSN) is a challenging area of research due to the instability of the water field. Due to the characteristics of the water environment, there are certain considerations which must be taken into account before the establishment of marine based wireless sensor networks. These include the deployment of wireless nodes (WNs), energy c...

Design and Implementation of Wireless Camera, Communication, and Control Modules for a Transformable Unmanned Aerial Vehicle

In this paper, we present the design and implementation of the wireless camera component, communications, and control components for a gun-launched, transformable Unmanned Aerial Vehicle (UAV). The transformable UAV is designed to be able to detect standard targets. In addition, the transformable UAV can be converted from a gun-launched projectile transformed to a UAV, and bevisually guided to ...
