A proposed mobile architecture for a distributed database environment

Much research has been devoted to mobile computing and database query management with the advent of portable computers and wireless communication systems. This paper proposes an architecture based on current mobile models, but with the addition of a mailbox, which serves as a storage area for the mobile hosts. Mobile Hosts (MHs) and Mobile Support Stations (MSSs) are connected over a wireless virtual subnet, and the MSSs are in turn connected to a wired static network. The architecture uses the TCP/IP protocol for communication in a mobile computing environment. Cellular providers (CP), the mobile network, and supporting hardware are defined and then assembled into a detailed example which traces the database query through the
