CAS4UA: A Context-Aware Service System Based on Workflow Model for Ubiquitous Agriculture

摘要

Practical automation in agriculture can save the time of the cultivation and increased the productivity. Generally, because agricultural environment is very changeable, the natural elements has to be considered in the autonomic cultivation process. Recently, the workflow model has been used as an effectual service automation model in traditional business environment, Web service environment, and ubiquitous computing environment. This paper proposes CAS4UA, which is a context-aware service system based on a workflow model for agriculture. The suggested system uses a workflow model to offer an automatic and context-aware service for ubiquitous agriculture, and to support the ubiquitous agriculture based on USN/RFID. To do this, the system uses a workflow model including various agricultural context information. Through the workflow model, the suggested system can dynamically and automatically control a service flow according to the changeable conditions in agricultural environment. Therefore, the proposed system can be useful in developing a smart service or automating work processes for ubiquitous agriculture.
