Resource-Oriented Architecture for Smart Home Operations Management Platforms

Until recently, Smart Home technologies are still not widely deployed in most peoples living spaces. The main reason is that operations management mechanisms for Smart Home such as remote deployment, monitoring, and maintenance are not well-studied and only a few attempts have so far been made toward this aspect. CWMP, proposed by Broadband Forum, is a promising standard for realizing a Smart Home operations management platform. Previously, we have investigated real-world operations management issues of Smart Home services, namely, newly installed, module purchasing and download, service start, service update, service diagnosis, failure recovery, usage statistics, and billing. After examining CWMP in detail, several issues of CWMP, namely, poor performance and scalability, poor domain model design and inappropriate web callback architecture, have been identified. The objective of this paper is, therefore, to deal with the issues mentioned above by suggesting a set of RESTful ways to refactor the CWMP-based operations management platform. The overall approach is based on the RESTful architectural style. The proposed architecture has been realized as an operations management platform prototype. Validations and experiments are performed to verify the effectiveness of the proposed architecture.
