Development approaches of smart space service components based on Web Services

Introducing component-based development (CBD) method, a smart space service component system supporting and enhancing mobile robot is designed, with basic structure and interaction modes proposed for service components, based on which cross-platform service invocation is realized for robot, thus solves the assistant resource´s diversity and heterogeneity problems. Service component encapsulates assistant resource´s function into shared service and provides open service access and invocation on smart space´s communication network through contractually specified service interface and description. It supports independent deployment, and is subject to third-party composition. Principles and typical implementations are presented in detail on developing service component for assistant resource and service invocation client for mobile robot, applying Web Services (WS) middleware technique.
