Interoperability Provision of IoT Data Protocols on Top of Virtualized Infrastructure

This article focuses on IoT interoperability challenges that limit the applicability of IoT-related services due to the variety of IoT data protocols utilized by different sensors and data nodes. Through the agility brought by virtualization, which allows gateway functions to be deployed on demand in an agile manner, this chapter discusses the concept of interoperability provision over heterogeneous IoT data protocols. More specifically, this chapter discusses the problem of interoperability in IoT domains by introducing the most popular IoT data protocols that are commonly used today. Then, a proposed solution is described based on the agility offered by virtualized infrastructures with SDN/NFV capabilities. The basic functionalities of these technologies are briefly presented and finally a proposed approach towards the deployment on-demand of date protocol GWs is described.
