Interoperation among IoT Standards

This article presents generic IoT (Internet of Things) reference architecture proposed by standard organization. It compares different IoT reference architectures proposed by different standards institutes, specially emphasizing lightweight requirements of IoT reference architecture. These architectures define multiple interfaces. Functionalities of proposed interfaces are compared here to enable an understanding regarding the scope of interoperation among different IoT standards. Finally, future scopes for standardization in IoT are presented.
