The vehicle exhaust gas emission is directly related with the quality of air. This paper describes the research and development of an ZIGBEE based exhaust gas detection system applying the service oriented architecture for the purpose of environmental protection. An edge engine supporting the EPC global ALE specification, a complex event processing engine dealing with the complex streaming ZIGBEE events and service bus, which are involved in the architecture of the system, are discussed both separately and in a whole picture. The edge engine is composed of four modules, which are kernel module, device management module, events filter module, and configuration module.
