The ubiquitous provisioning of internet services to portable devices

The Ubiquitous provisioning of internet services to portable devices is discussed. Portable devices require middleware that exhibits nontraditional properties, such as location awareness and context adaptation, and that supports their accessibility to traditional and new services. The middleware should give services to the client access device's specific characteristics. Middleware solutions should automate device configuration management to free users from knowing and interacting with the implementation details specific to different devices. The SOMA-based middleware for portable devices consists of the components such as the shadow proxies, service adapters, device-specific clients, and the Profile Manager Service (PMS).
