International Standard Organizations such as ITU(International Telecommunication Union) and IETF (Internet Engineering Task Force) are proceeding standardization for various applications and protocols to provide video-conference and multimedia conference services on a variety of networks. Remote device control among these protocols is provided with various capabilities as well as device control to multimedia conference. This protocol for remote device control is standardizing as H.282 recommendation which is specified as core service for the configuration and control of remote device to multimedia conference. The H.282 recommendation does not specify the use of a particular transport protocol. That is, T.120 multimedia conference uses T.136 and H.323 video conference uses H.283 for the transport of H.282 protocol. The introduced system in this paper is based on H.282 and is implemented to be capable of remote device control within the framework of H.323 using H.283. Also, it is shown that a variety of services in the specification of the standard are satisfied through experiments.

In this paper, we propose a remote control station based on the awareness of various combat field situation in order for operating multiple unmanned ground vehicles. Our remote control station is capable of sending a variety of messages designed for carrying out the skillful movement for collaborate among unmanned ground vehicles, gathering the information related with combat field situation, and completing the assigned missions which are described by operator in advance. To verify the effectiveness of our proposal, we develop the sophisticated remote control station and conduct a great many remote operating tests for multiple unmanned ground vehicles.

The demand of remote control and monitoring for efficiency and applications of LED streetlight is increasing continuously because the demand of LED streetlight was increase last few years. Existing street light remote control system is wired using a power line network. The wireless connection exists, but due to its low data transmission rate, it cannot support specialized applications. It can only support simple control and monitoring. In this paper, we propose a system that uses a IEEE 802.11s wireless mesh network based on WLAN, as a backbone network for remote control and monitoring of the LED street lights along with other specialized applications. Using the wireless mesh network for remote control and monitoring the LED street lights, the same can be used to act like a public Wi-Fi access point. We have designed Wi-Fi integrated LED streetlight controller and implemented our system. We evaluated the performance of our system on a real test bed. Our proposed system is expected to perform the role of a U-city infrastructure by utilizing the wireless mesh network.

Existing web-based system management software solutions show some limitations in time and space. Moreover, they possess such as shortcomings unreliable error message announcements and difficulties with real-time assistance suppers and emergency measures. In order to solve these deficiencies, Wireless Remote Control System was designed and implemented. Wireless Remote Control System is able to manage and monitor remote systems by using mobile communication devices for instantaneous control. The implementation of Wireless Remote Control System leads to these security Problems as well as solutions to aforementioned issues with existing web-based system management software solutions. Therefore, this paper has focused on the security matters related to Wireless Remote Control System. The designed security functions include mobile device user authentication and target system access control. For security verification of these security functions introduced CPN(Coloured Petri Nets) which is capable of expressing every possible state for each stage. And then in this paper was verified its security through PI(Place Invariant) based on CPN(Coloured Petri Nets). The CPN expression and analysis method of the proposed security function can also be a useful method for analyzing other services in the future.

A new method to control a remote robot with PDA and wireless network is presented. The needs of remote control systems using a home network environments are increased in these days. To solve the shortage of IP address in network, authorized TCP/IP and unauthorized TCP/IP address are used. The unauthorized TCP/IP is obtained by using MAC Address in the system and Network Layer. The model in the system is similar to Sever&Client in structure. Using this system, it is very easy to combine one network device with other network system. A robot system and PDA are used to show the effectiveness of the control system in home network environments.

This paper begin a new approach in the water-gate control using radio communication. The dissertation is on the controllable device development of water-gate in the remote distance from water-gate trough the transceiver by radio communication. The proposed water-gate control device is simpe in structure, an suitable for implementation of water-gate control in the remote distance. The remote controller water-gate device inspected the up and down motion of water-gate through the LCD displayer, so that it was very safety driving about the surroundings imformation, over loading and position of water-gate, and so on.

최근 가정에서 사용되고 기기 중 원격제어기(Remote controller)로 제어가 가능한 기기가 늘어나고 있다. 이에 따라 여러 기기들이 있는 경우 사용자는 기기들을 동시 제어하려 할 때 제어하고자 하는 제어대상에 맞는 원격제어기를 찾기 위해 많은 시간을 소비하는 경우가 일반적이다. 이러한 불편함이 증가함에 따라 통합원격제어기(Universal remote controller)의 보급이 증가하고 있으나, 여전히 여러 기기를 동시제어하고자 할 경우 제어코드의 입력 등 복잡한 절차를 걸쳐 사용할 수 밖에 없으며, 이러한 점은 결국 통합원격제어기의 사용성을 현저히 약화시킨다. 본 고에서는 인간이 제어대상기기를 제어하고자 하는 의도를 원격제어기에 전달하는 여러 방법 중 인간이 물체를 인식하는 것과 동일한 메타포인 직관적인 '지시(Pointing)'법을 사용하여 실시간으로 다중기기를 통합 제어하는 방법, 즉 지시통합제어방법(Point and Control)에 대한 센서 및 하드웨어구조를 설명하고, 구동방식을 제안한다.

A mobile robot system is developed which is remotely controlled by a haptic master called ‘PHANTOM’. The mobile robot has 4 ultrasonic sensors and single CCD camera which detects the distance from a mobile robot to obstacles in the environment and sends this information to a haptic master. For more convenient remote control, haptic rendering process is performed like viscosity forces and obstacle avoidance forces. In order to show the effectiveness of the developed system, we experiment that the mobile robot runs through the maze and the time is checked to complete the path of the maze with/without the haptic information. Through this repeated experiments, haptic information proves to be useful for remote control of a mobile robot.

In this paper, we design a mobile phone based remote control system for PC using SKT WPAN platform and compare the presented platform with that of Windows Mobile. The usability of WPAN is one of the main issues which should be considered for the ubiquitous services. For easy development and easy use of the WPAN applications, SKT WPAN platform provides abstract WPAN APIs and WPAN Application Manager for ubiquitous services. In this paper, we implement a remote control application using the WPAN platform and show the validity of the platform comparing with other platforms. In the implemented application, we use WPAN abstract APIs on the mobile phone side and a general Bluetooth APIs on the PC for a connection between phone and PC. Through the implementation and comparison, we show that the WPAN application can be easily developed with WPAN platform.
