With the constant improvement of electrical equipment automation level, unattended electric power system node becomes increasingly popular. In addition, because of the ever-increasing industrial demand for electricity, electric power infrastructure becomes larger and larger, equipment and transmission link structure are more and more complex, all kinds of faults emerge one after another and adm...

Mobility of users, transmission of signals through open-air, the requirement of low power consumption by mobile users and smaller data storage area limitation in mobile equipment make mobile wireless networks more vulnerable to security threats like eavesdropping and unauthorized access. This paper proposes a new set of security protocols to enhance the access and data security features of GSM ...

This paper analyzes the pricing of fixed and mobile peer-to-peer application. In Fixed Internet the peer-to-peer application is very popular. In mobile Internet the peer-to-peer application has it own characteristics. Since the mobile set is personalized equipment, the mobile peerto-peer application will concern something more personal. Defer from the peer-topeer application of file sharing on ...

applications are mobile communication terminals, digital consumer equipment, and multimedia systems. One example of digital consumer equipment is the digital still camera. Hitachi has developed a digital camera system based on the SH-DSP (Fig. 1). ABSTRACT: Recently sales have grown markedly in the field of mobile communication terminals such as global system for mobile communications (GSM), pe...

Wireless communication technologies are pervasive in today’s everyday environment. Together with the ever-dropping cost for equipment relying on such technology, this abundance gives rise to a wealth of applications well beyond communication itself. Utilizing communication technologies in the context of mobile sensing seems to be an especially promising approach, as mobile phones and other pers...

A modern world contains varieties of electronic equipment and systems like: TV, security system, Hi-fi equipment, central heating systems, fire alarm systems, security alarm systems, lighting systems, SET Top Box, AC (Air Conditioner) etc., we need to handle, ON/OFF or monitor these electrical devices remotely or to communicate with these but, if you are not at the home or that place and you wa...

The cell phone though the mobile communication system is proved to be an advantageous method of communication over wired communication, there is another problem that is the mobile phones get lost or get misplaced. The losses are increasing day by day and there has been very little effort that has been done to obtain the lost mobile phone. The main scope for this paper is “The proposal for the d...

This project deals with the problems of utilization of mobile equipment working in the biomedicine field, particularly telemedicine. The whole system is based on the architecture of .NET Compact Framework, and other products, such as SQL Server by Microsoft too. The mobile equipments are used primarily for measuring and processing of data from the sensors and their visualization as a graph. The...
