Dynamic Binding in Mobile Applications: A Middleware Approach

By separating binding concerns from application logic, the Colomba approach exploits metadata to let mobile applications adapt to dynamic environments. Colomba separates service logic from binding management. This permits developers to code, change, and reuse service components and binding strategies independently of each other. Administrators can express binding strategies at a high level of abstraction in terms of declarative policies. In particular, Colomba supports a dynamic binding management that requires: Context awareness is the knowledge of application-specific attributes, such as user preferences, level of trust, subscribed services, and access device characteristics. Users can refer to a set of resources determined by context information. Location awareness is the knowledge of the physical position of the user or device connection to the network infrastructure. Available resources depend on location information.
