Abstract

ETSI M2M Platforms provide general infra services for machine-to-machine communication. In this paper, we propose a service-level integration methodology which can integrate a ETSI M2M platform with heterogeneous web applications based on WSDL 2.0. Considered heterogeneous web applications are the ones that use SOAP, HTTP and CoAP protocols for inter-communication. The proposed WSDL 2.0-based service-level integration methodology includes the followings; (1) We present a method of how to describe standardized M2M platform service interfaces into a WSDL 2.0 document. (2) A proposed web client generator is used to generates SOAP, HTTP and CoAP client codes from the WDSL 2.0 document. (3) We propose protocol conversion proxies which translate protocols into other protocols in web service run-time.

ETSI 표준 M2M 플랫폼은 M2M을 위한 공통 서비스를 제공하는 플랫폼으로, 본 논문에서는 WSDL 2.0 표준 문서를 이용하여 ETSI 표준 M2M 플랫폼 서비스를 SOAP, HTTP 및 CoAP 형태의 웹 서비스로 제공 가능하게 함으로 서비스 차원에서 이종의 웹 애플리케이션과 연동하기 위한 방안을 제시하고 있다. 본 논문에서 제안하는 서비스 차원의 통합 방안은 (1) M2M 플랫폼의 서비스 인터페이스를 WSDL 2.0 문서로 기술하는 단계, (2) 제시된 웹 클라이언트 생성기에 따라 WSDL 2.0 문서를 토대로 SOAP, HTTP 및 CoAP 웹 클라이언트를 생성하는 단계, (3) 제시된 웹 프로토콜 변환기로 웹 서비스 실행 시 이종의 프로토콜을 상호 변환하여 주는 단계를 포함하고 있다.
