Current maritime on-board communications have to be enhanced for safety and security, where ubiquitous technologies can help, together with providing comfort and convenience to the crew and passengers. Employing wireless sensor networks on board is one recent practice of implementing ubiquitous technology for ships, where further study is needed because of the connectivity challenges. Meanwhile, it...
For such an environment, such as radiation, pollution, dangerous, distributed environment where the staff is not easy to reach, it is difficult to complete data collection and real-time monitoring through the traditional manual method. The study of remote wireless monitoring system, which based on the MCU (micro control unit programming) and GPRS (General Packet Radio Service) architecture, can well...
As more network-capable devices are developed, it becomes easier for us to remain connected to our friends, colleagues, and even our homes. Unfortunately, it becomes easier for unintended third parties to remain connected to us as well. The impact of this has been limited by our proximity to the third party (i.e. the same local area network) -- until now. The Internet Protocol version 6 (IPv6) includes...
In the remote, hazardous, distributed and external environment, such as radiation source, pollutant source and pipeline of petrol, water and gas, it is difficult to collect and send the necessary message in real-time by traditional monitoring ways. This paper briefly describes the design of remote wireless monitoring system based on MCU (Micro-programmed Control Unit) and GPRS (General Packet Radio...
Remote monitoring system based on GPRS is a modern monitoring system which is compose of radio communication technology, signal collection and computer network technology. This article introduces a wireless coal mine monitoring system based on GPRS communications technology. This system proposed in this paper has achieved a good result in the test.
DNS is an important application as a part of the procedures of most Internet applications, which means quality of DNS directly influences quality of these applications. In order to monitor and analyze user perceived end-to-end quality of DNS applications, two key parameters of DNS quality were chosen. A distributed system NQM was used to monitor various types of practical DNS services by deploying...
This paper designs a wireless power meter system based on GSM network; the main communication way is GPRS and secondary SMS. The user can choose the different transfer modules based on different demands and can choose the Local network, dial network, ISDN, ADSL to connect into network. It accomplishes the hardware and software design in GSM network collector and the meter system software.
The significance of forest fire monitoring was determined by the importance of forest resource and the destructive of forest fire. In the paper, according to the limitation of traditional forest fire monitoring schemes, a new wireless network implementation scheme oriented to forest fire monitoring was presented based on GPRS communication technology and ZigBee technology. The related hardware schemes...
Due to the rapid expansion of road and highway system around the world, there is a growing demand to monitor vehicle traffic patterns and road status by jurisdictional agencies charged with maintaining roads and ensuring the safety and usability of various highways within their jurisdictions. The feasibility of performing effective monitoring relies on cost, complexity and scalability of the traffic...
The traditional monitoring mode can't meet existing security requirements, so an effective monitoring method is needed to ensure that important equipments and peripheral situation in distribution network are visualization and control ability. This paper introduced a new system based on embedded system, video compression and 3G network, which can transport video image to remote monitoring center and...
Based on the wireless data transmission technologies, the vehicle-mounted wireless transmission terminal is able to provide reliable, up-to-date and accurate transport information for the moving vehicle, which contributes towards efficient road use, better traffic flow and greater road safety. The design of this vehicle-mounted wireless transmission terminal is based on ARM embedded technology and...
With today's widespread deployment of wireless technologies, it is often the case that a single communication device can select from a variety of access networks. At the same time, there is an ongoing trend towards integration of multiple network interfaces into end-hosts, such as cell phones with HSDPA, Bluetooth and WLAN. By using multiple Internet connections concurrently, network applications...
A novel video monitoring system is proposed to provides a more excellent solution for security. The core architecture of this system is constructed by using wireless mesh network (WMN), which has emerged in recent years. WMN is dynamically self-organized and self-configured and can provide better services than other wireless networks. The basic network of this system is divided into two layers: access...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
