A Layered Protocol Architecture for Scalable Innovation and Identification of Network Economic Synergies in the Internet of Things
Tilman Wolf, Anna Nagurney · 2016
Many solutions to important societal problems relating to the environment, health care, transportation, etc. seek to utilize the promises of the Internet of Things (IoT), where sensing, computation, and actuation merge the physical world with the computational world. To date, many such solutions have focused on a single problem domain and require dedicated sensor and actuator infrastructure. This vertical integration makes the development of innovative, novel solutions costly and difficult to deploy. An architectural approach to addressing this challenge is to enable horizontal integration, where sensors and actuators from different applications can interconnect with any computational IoT application. In order to isolate complexities and to support heterogeneous systems and software, it is necessary to provide clear abstractions. We present such abstractions in the form of a layered protocol architecture that describes the necessary interfaces. Beyond technical challenges for horizontal integration, this paper also addresses network economic considerations since the various entities owning and operating sensors and actuators need suitable economic motivation to participate in such an approach. We believe that this work provides a conceptual foundation for future, scalable IoT solutions.
