Transaction Processing with mobile collaborative works.

The theme of this research is mobile transaction processing systems, focusing on versatile data sharing mechanisms in volatile mobile environments. The rapid growth of wireless network technologies and portable computing devices has promoted a new mobile working environment. A mobile environment is different from the traditional distributed environment due to its unique characteristics: the mobility of users or computers, the frequent and unpredictable disconnections of wireless networks, and the resource constraints of mobile computing devices. The authors have developed a mobile transaction processing system for MOWAHS. Especially, we have successfully designed, implemented, and tested several important system components such as the mobile locking system and the mobile data sharing system
