Design and implementation of sync engine for automatic installation system of PDA application programs

The development of Internet technology onto mobile communication technology has brought us wireless Internet, which is growing into a popular service because of it´s added convenience of mobility. Wireless Internet was first provided through cellular phones, but the current trend is moving toward PDA (personal digital assistants), which have extended functionality. Applications to increase the functionality of PDA are constantly being developed, and occasionally application software must be installed. Also, when a PDA´s power supply becomes fully discharged, all data stored in the RAM (random access memory) becomes obsolete, and programs must be reinstalled. This paper presents an automated application program installation system, IPMS (installation program management system), designed as a solution to the problem of PDA users having to do the installation of application programs on their PDA themselves. When this engine is applied, PDA users can save time and effort required for installations, an added convenience, and application software companies can save on costs previously needed to create materials explaining the installation process.
