초록
스마트 홈 인프라를 기반으로 유비쿼터스 컴퓨팅 환경을 구축하기 위해, 여러 연구기관과 산업체에서는 홈 네트워크에 대한 다양한 연구를 진행하고 있다. 이로 인해 다수의 홈 네트워크 미들웨어들이 제안되었으며, 이는 홈 네트워크 표준화를 지연시켰고, 이러한 표준화의 지연은 이기종 미들웨어 간 상호운용성 문제를 해결할 수 있는 미들웨어 브리지를 요구하였다. 현재 두 미들웨어에 대한 상호운용성을 지원하는 일대일 브리지, 다수의 미들웨어에 대한 상호운용성을 지원하는 일대다 브리지 등 여러 미들웨어 브리지에 대한 개발과 상호운용성 지원 기법에 대한 연구가 진행되고 있다. 하지만 기존의 시스템과 기법들은 특히 스마트 홈 환경에서 요구되는 동적 확장성과 성능에 대한 고려가 부족하다. 미들웨어 브리지는 전문적인 지식이 없는 사용자를 위해 브리지의 수정 없이 쉽게 새 미들웨어를 추가할 수 있는 브리지 확장성을 제공해야 한다. 또한 브리지는 메시지 집중을 해결할 수 있는 부하 분산 기법 역시 제공해야 한다. 본 논문에서는 홈 네트워크 환경에서의 동적 확장성과 부하분산을 위한 다중 미들웨어 브리지(Multi-Middleware Bridge, MMB)를 제안한다. MMB는 분산 구조를 통해 브리지 확장성과 부하 분산 기능을 제공한다. 또한 이에 대한 구현과 평가를 통해, 상호운용성 지원 기능과 브리지 확장성, 부하분산 알고리즘의 성능을 검증한다.
Abstract
For implementing the ubiquitous computing environments with smart home infrastructures, various research on the home network have been performed by several research institutes and companies. Due to the various home network middleware that are developed recently, the standardization of the home network middleware is being delayed and it calls for the middleware bridge which solves the interoperability problem among the heterogeneous middlewares. Now the research on the scheme for interoperability and the development of the various bridges are in progress, such as one-to-one bridge supporting interoperability between two middlewares and one-to-many bridge supporting interoperability among the multi-middlewares. However, existing systems and schemes does not consider the dynamic extensibility and performance that is particularly needed in the smart home environments. The middleware bridge should provide bridge extensibility with zero-configuration for non-expert users. It should also provide the load balancing scheme for efficient and proper traffic distribution. In this paper, we propose a Multi-Middleware Bridge(MMB) for dynamic extensibility and load balancing in home network environments. MMB provides bridge scalability and load balancing through the distributed system structure. We also verify the features such as interoperability, bridge extensibility, and the performance of the load balancing algorithm.
