Mobile Transaction System for Supporting Mobile Work

Abstract

This paper presents a mobile affiliation model that supports sharing information among mobile transactions. The model allows mobile hosts to form a dynamic workgroup, called mobile affiliation, by taking advantages of wireless communication technologies. In the MOWAHS transaction system, mobile transactions can exchange data in a mobile sharing space, called export-import repository, in both synchronous and asynchronous manner. The database consistency in the mobile affiliation is ensured by export and import transactions. We show that our mobile affiliation model has superior power for supporting mobile transactions by taking into account the disconnection of wireless networks, the limitation of computing power of mobile devices, and the mobility of computing hosts.
