This paper introduces the design plan of a distributed control and management system for power devices, and puts emphasis on the hardware composition and working principle of the system. The system is divided into two parts: field devices and monitoring center. The former uses ARM to collect data and control MC35, a module of GPRS; the later uses Browser/Server to realize centralized management of...
With the development of sensor, wireless mobile communication, embedded system and cloud computing, the technologies of Internet of Things have been widely used in logistics, Smart Meter, public security, intelligent building and so on. Because of its huge market prospects, Internet of Things has been paid close attention by several governments all over the world, which is regarded as the third wave...
Mobile Streaming is a very attractive multimedia service that has many applications; in this paper a model of a mobile voice message (MVM) service has been proposed using JAVA ME, whose aim is to create and deliver streaming of voice messages to mobile phones. The MVM model is based on a layered client-server architecture. MVM is designed to operate in wireless data networks, such as Wi-Fi, GPRS and...
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.
Nowadays, users of mobile phones generate too many files that have to be frequently downloaded to an external storage repository, restricting the user mobility. This paper presents a File Transfer Service (FTS) for mobile phones with scare storage resources. It is a support that can be used through a set of functions (API) that facilitates file transfer between mobile applications and external storage...
Current mobile devices such as mobile phones and PDAs are able to run applications that can demand a considerable storage space. When these devices run out of local memory, they require backing up their files in an external storage device, which could restrict the user mobility. This paper presents an Adaptive File Transfer Middleware (AFTM) for mobile applications. This middleware eases the transfer...
The large scale adoption of mobile phones brings a merging mobile commerce market. Most wireless applications are based on GPRS to provide services in wide areas, while some location based services are based on Bluetooth to enable mobile users to enjoy proximity services. However, very few systems marry the two communication technologies together to provide a more pervasive wireless system with which...
As a smart consumer, there is always a need for us to identify the quality of the goods we want to buy, such as trying to choose the better mango amongst the others in a fruit market. With the popularity of the mobile phone and the maturity in wireless messaging technology, it is no more a dream for us to get the information we want anywhere, anytime. This paper proposes a new mobile data service...
With the maturation and acceptance of broadband wireless technology and standards (e.g. mobile WiMAX, EVDO, HSPA), forward-looking service providers are beginning to augment their coverage with new broadband wireless networks and offering new higher-speed services. At the same time, we see that on-the-go transit and ride-sharing vehicles are beginning to see a market for offering wireless access throughout...
