IoT systems based on SOA services: Methodologies, Challenges and Future directions

Things fitting to the Internet to provide and access online information are denoted as Internet of Things (IoT). A huge number of networks shall be required to convert this information into meaningful interpretations. SOA based services are used to develop large enterprise systems and therefore play an important part in Internet-of-Things domain. In this paper, the existing methodologies/ architecture/ techniques, challenges and future directions conducted on the usage of services and Service Oriented Architecture (SOA) in IoT based systems have been discussed. This paper presents a comprehensive review of more than 50 recent research work done in IoT services and classifies it into five categories which are based on the: usage in real world applications, architectures used, different IoT features, IoT service modeling and discovery and platforms used. The paper also provides the research areas and problems that can be explored in future by the research community.
