A Context-Aware Service Model Based on the OSGi Framework for u-Agricultural Environments

Abstract

In ubiquitous environments, many services and devices may be heterogeneous and independent of each other. So, a service framework for ubiquitous environments have to be able to handle the heterogeneous applications and devices organically. Furthermore, because demand changes in ubiquitous environments tend to occur very dynamically and frequently, the service architecture also has to handle the demand changes of services in ubiquitous computing environments well. Services and devices in ubiquitous agricultural environments also have each other’s different characteristics. Therefore, we need a service framework which can negotiate the heterogeneous characteristics of the services and devices for context-aware services in ubiquitous agricultural environments. In this paper, we propose an OSGi framework-based context-aware service model for ubiquitous agricultural environments. The proposed service model is based on OSGi framework, which can support various context-aware applications based on RFID/USN in ubiquitous agricultural environments regardless of what sensors and devices in agricultural environments are. Therefore, the proposed service model can fast reorganize and easily reuse existing service resources for a new agricultural service demand without all or big change of the established system architecture of the agricultural environments. Especially, the proposed service model can be greatly helpful in the developments of context-aware agricultural services in various cultivation environments equipped with each other’s different sensors.
