 +Due to the popularity of the Web, Web and related technologies have a profound impact on the research and development of the Internet of Things (IoT) and Smart Environments. Consequently, the concept of WoT (Web of Things) emerges by combining the Web, REST (Representational State Transfer), and IoT. Similar to other service-oriented systems, it is also essential to manage and coordinate software and hardware components dynamically. Among the existing service management mechanisms, the mDNS/DNS-SD specification developed by the IETF is considered to be promising as a service management mechanism for WoT, because it extends the DNS packet format and mechanisms and can be used without additional configuration of other system components. Also, the encoding scheme of DNS is relatively compact and thus requires less memory. However, mDNS/DNS-SD lacks many core service management functions such as service description and service invocation. Besides, the query mechanism in DNS-SD in inflexible and inefficient. As a result, this project aims to propose an integrated solution to deal with the problems mentioned above. We are going to design a mechanism that embeds the W3C WTM standard into DNS-SD, provides service access based on the REST principle to implement WoT service invocation mechanism, and develop flexible preference expression service search. Finally, we are going to optimize the performance of interactions among service components and verify the functionality, performance and practical feasibility through experiments and application scenarios. Finally, the research results will be implemented as a prototype system and design cases/scenarios to be referenced by future researchers or industry R&D teams.
