An enterprise that controls the physical processes such as the execution of logistics, manufacturing or building automation generally involves an embedded system that interconnects a range of different devices. Internet of things helps millions of devices to be interconnected so that it can effectively cooperate with each other. An IoT helps make various devices interoperating; therefore, a service-oriented approach is one of the promising solutions. According to this article, shortly, every enterprise based infrastructure will be service oriented, thus, implementing the embedded system in the organisation for combining system in the cross-layer form can improve the performance as well as the reactivity of the industrial processes such as logistics, manufacturing and others. This service-oriented infrastructure can help make the information available in the real-time scenario based on the asynchronous event.
For identifying the integration capabilities of the IoT, an architecture need to be developed which need to be involved in the application interface, device management, service management, platform, abstraction, security and the devices. For making the embedded system of the hardware and software to perform its work, it is necessary for hiding the heterogeneity of the software, hardware, format of the data and communication protocol. In that case, standard communication needs to be developed via web services in every layer so that cooperation can be developed in the embedded system. This article offers a design of the infrastructure with the help of which the embedded system can perform its tasks more cooperatively. The first element of the infrastructure mainly includes the eventing element, which is the implementation of the WS-brokered notification standard. This element primarily associated with subscribing the functionality and implementing publishes for distributing the information regarding the events of interests. The next component of the infrastructure is the invocation handler that is associated with implementing the functionality so that it can act as the intermediaries for the facilitation of service invocation. The main reason for implementing W.S. everywhere is it offers a higher level of flexibility. The next element is the service catalogue. The main goal in performing the service catalogue in the infrastructure is it helps in offering a search engine which allows the application to look for different services by putting the queries.
According to this article, the next element is the composed service routine which is associated with communicating the service partners over the partner links. CSR hosts different composed services based on the capacity of devices such as CPU power or RAM. The next element is the service monitor, which is associated with storing live, fast-changing and update data regarding the currently used instances of service. This storage is generally considered as the in-memory data structure rather than a database structure. The next element is monitoring and inventory, which is composed of different components that include device monitor, device repository, discovery and the middleware historian. The next element is the service lifecycle manager, which consists of two sub-components such as service mapper and service implementation repository.
Device services proxy performs the actual tasks by integrating different category of heterogeneous devices. Device service injectors are the next element which is associated with executing the deployment levels during processing deployment lists by service mapper. The last component of the infrastructure is the enterprise services proxy factory which offers the interfaces for creating the virtual devices that act as the intermediaries among enterprise services and device level. Therefore, from the above infrastructure, it can be said that it is event-based and mainly interact with the external entities along with internal communication so that it can strongly couple IoT with enterprise services.

In this present era, IoT has become one of the mandatory technologies in the industrial system to make it more powerful. IoT is the dynamic global network infrastructure that has self-configuring capabilities based on the interoperable and standard communication protocol where the virtual and physical things have the identities, virtual personalities and physical attributes. There is a growing level of interests of people in using IoT technologies in different industries such as food processing, agriculture, security surveillance, environmental monitoring and others. This article mainly provides diversity if the current IoT research in enterprises and identifying the opportunities and threats for future researchers. IoT is considered as one of the network infrastructures that mainly includes various connected devices which rely on the communication, sensory, information processing technology and networking. RFID is one of the foundation technologies of the IoT. With the help of the readers of RFID, any object that attaches an RFID tag can be identified, monitored or tracked. The wireless sensory network is another foundational technology of IoT. Presently, IoT has achieved the attraction of different industries such as manufacturing, retailing, logistics and others. According to the article, wireless communication, sensor network technologies, Smartphone and other networked object or thing is being involved in IoT.
For this reason, many organisation and countries have become interested in the standard of IoT because it offers tremendous economic benefits shortly. U.K. government has launched its £5 million projects for developing IoT. China has taken a severe vision of IoT, and they have invested £800 million in the IoT industry.
This article clearly describes the fact that IoT is aimed at connecting different thing over the network by integrating heterogeneous devices or systems. A service-oriented architecture is a technology that is highly useful in supporting IoT. Few ideas are there that have been proposed for creating the SOA architecture for the IoT based on the business needs, selected technology and technical requirements. As an example, it can be said that international telecommunication union has recommended that the architecture of IoT need to consist of sensing, accessing, middleware, networking and application layers. From the functionality perspectives, it can be said that there are mainly four different layers in the SOA of IoT that is sensing layer, networking layer, service layer and the interface layer. Presently, IoT is using in the healthcare industry, safer mining production, logistics and transportation, fire fighting and many more. Despite the full application of different sector, there are still different research challenges of IoT that are creating difficulties in applying IoT in various industries. Problems that can be created in using IoT in different sectors are technical challenges, information security related challenges and the standardisation related challenges. There are good future scopes for IoT by integrating social networking with the IoT solution, developing green IoT technologies, combining cloud computing with the IoT, employing A.I. and many more. This paper reviews different current researches about IoT from the perspectives of the enterprise. This article has introduced the SOA model and the backgrounds, and then it discusses various types of underlying technologies which can be used in the IoT.
