The role of autonomous aggregators in IoT multi-core systems

The Internet of Things constitutes a prominent field, integrating smart devices and people into complex systems that may vary in scale. To ensure the constant availability and performance of provided services, alternative distributed architectures should be explored, promoting system scalability. To this end, alternative architectures for the IoT are proposed. Commonly an intermediate layer consisting of aggregators, controlling sensors and actuators and providing a service interface to IoT applications, is incorporated in such architectures. To promote scalability of IoT systems, aggrerators should to operate as autonomous entities. For an aggregator to become autonomous, self-management policies should be enforced. In the paper, we discuss autonomous aggregator software, running on multi-core IoT systems to efficiently implement such policies. A demonstrator for smart buildings, developed as a proof of concept for the proposed concepts, is also presented.
