Leveraging different application styles in mobile business

ABSTRACT

Nowadays, nearly every field worker has a mobile phone and/or another kind of a mobile device and an abundant hardware infrastructure for mobile business applications exists. The common advances in the area of wireless communication technologies facilitate the realization of mobile business applications; however, the utilization of this infrastructure is an expensive task due to resource restrictions and heterogeneity of mobile devices. Specialized applications have to be developed for each kind of mobile device.

Based on the service-oriented paradigm, we designed a reconfigurable middleware for mobile devices which deals with the respective heterogeneity. Service-oriented architecture (SOA) allows to invoke services running on remote devices, whereas the n-tier application approach is separating applications into particular tiers. Up to now, the location of each tier in multi tier architectures was static. With our approach, the runtime redistribution of tiers is possible for each user, application, or device without additional implementation efforts.

In this paper we present the middleware design and our prototype RecSO. We describe in depth the service invocation and with a scenario show the advantages of our approach.
