Web Services and Internet of thingsInternet ofthings(IoT) is a field that includes many technologies which helps in creationof a smart world by making things easy to humans.

In this, humans interact withuseful web services built with the help of technologies like embedded systems,wireless (network) communication. IoT can be applied to any real life/ businessapplications that has scope to become smarter. In general, it can be applied tosmart cities, smart transportation, smart industries etc.

by using network of devicesembedded with sensors, software etc. to communicate among themselves. The maingoal of IoT is to come up with an innovative technology to form a bridgebetween people and objects anywhere in the world. A web service plays the roleof a software platform for IoT based protocols.Theunderlying architecture of a Web service is Service Oriented Computing which isused by web service to provide better communication among multiple computing units,business models thereby easing the application flow. These services can beaccessed by a URI and whose interfaces can be described and discovered by exchangingXML based messages vi internet based protocols is generally termed as a webservice. Usually, these services are independently developed and exposed tousers via Web infrastructure with standards like XML, SOAP, WSDL. Web Services in Internet ofthingsThe goal ofthe IoT is to connect everyday objects such as domestic appliances and embeddedsystems with each other under the internet connectivity.

This way, they form adistributed network with sensing capabilities that allow unprecedented marketopportunities. In the IoT domain, a web service plays the role of a softwareapplication that provides a platform for IoT based protocols. A web service hasproven to be indispensable in creating interoperable applications and hence theidea of embedding web services into smart things has opened huge possibilitiesof marketing new technologies. The main challenge to web services in IoT isthat the traditional web protocols might not provide seamless services inlow-power and inconsistent network oriented smart things. An extensive researchis being put into developing protocols that solve these challenges.

Fewprotocols like CoAP and EXI emerged to provide light weight web basedinteractions among multiple devices. Motivation In general,many services are composed to built a new services to the user. In this process,data from many Internet of Things devices are used to finally come up with thepurposeful and meaningful services to the user. There are many such deviceswith data being generated that is not organized, it is important to know and  take advantage of all such data in order tobuilt useful web services.

There are plenty of services being offered inInternet of things domain. These services are restricted using different controltechniques like by using roles and privileges in order to make sure thatservices are used appropriately by the proper users. And also there is hugeimportance given in Internet of things field for discovery of such usableservices.  Sources and Papers·      Castellani,M. Gheda, N.
