RESTFUL COMMUNICATION APPROACH

Abstract

There are devices performing variousfunctionsand providing services to other devices. These devices provide output in various formats like xml,html,csv,pdf etc. It becomes difficult to parse this data into required format as it requires extra overhead.To send this data we are considering two options namely SOAP services or RESTful Services.RESTful services are replacing SOAP services because of their various advantagesdescribed further in this paper,So to provide the interoperability between devices we suggest to use RESTful webservices susing json as output. REST is an architectural style to develop webservices which represent each device with an unique URI.We will discuss as to how we can use OAuth as a security mechanism for these webservices and how effective it is to use with IoTdevices.We provide general guidelines on how to design aREST API(Application programming interface)device description for machine-to-machine interactions. We will be discussing about the pull approach where only client can initiate communication andapush approach where a server can also start an interaction with clientbased on the triggers defined which in our case is a voice commandand how sall these fit in to define a complete communication approach
