With the rapid progress of information techniques, people should have a convenient environment and life. This study designs and develops a Web2.0-based Home-Appliances controL sErvice platform (WHALE), which is based on the standard of Devices Profile for Web Services (DPWS) and the service platform of Open Services Gateway initiative (OSGi). WHALE is designed and implemented for users to easily control home-appliances over Web2.0-based services. Users can use many kinds of handheld devices to get information and services of related home-appliances from the WWW platform. WHALE is a three-tier architecture, which consists of Device Detection and Registration Service Platform (DDRSP), Web2.0 Service Platform (WSP), and Common Service Platform (CSP). When DDRSP finds a new home-appliance, this homeappliance will be registered into CSP. CSP records related information and services which are provided by the homeappliance. WSP not only integrates and shows services of all home-appliances but also provides controlling interfaces to control the status of all home-appliances. All delivered messages are based on Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL). WHALE can be a reference model for developing home-appliances controller in the future.
