Toward an easy programming environment for implementing mobile applications: a fleet application case study using SyD middleware

Abstract

This paper describes the advantages of SyD (System on Mobile Devices), a middleware technology for mobile devices and e-services, in terms of technology and programming. Features of SyD are illustrated here through our prototype application, a complex communication system for a trucking fleet that operates an automated package delivery system. The fleet system has been implemented in three ways, with SOAP, with JDBC, and with SyD. Our implementation experience shows that SyD greatly simplifies coding by allowing heterogeneous devices, peer-to-peer communications, group transactions based on triggering events, and mobility support through proxies and directory service.
