内容简介：
The Internet of Things (IoT) is shaping the evolution of the future Internet. After connecting people anytime and everywhere, the next step is to interconnect heterogeneous things / machines / smart-objects both between themselves and with the Internet, allowing the creation of novel value-added services/applications. The IoT, as of future networks, will tend to be a multi-vendors, multi-services and largely distributed environment and where the risk of non-interoperability is high. Thus, it is vital to guarantee that systems and network components interoperate to unleash the full value of the IoT. It happens, that the IoT might be the final frontier for interoperability! Final, as it is possibly the place where interoperability is the most difficult to tackle due to the intrinsic and unavoidable nature of the IoT itself. Interoperability is hard as the IoT is: (i) high–dimensional, with the co-existence of many systems (devices, sensors, equipment, etc.) in the environment that need to communicate and exchange information; (ii) highly-heterogeneous, where these vast systems are designed for much different purposes and targeting diverse application domains, making it extremely difficult (if not impossible) to reach out for global agreements and widely accepted specification; (iii) dynamic and non-linear, where new Things (that were not even considered at start) are entering (and leaving) the environment all the time and that support new unforeseen formats and protocols but that need to communicate and share data in the IoT; and (iv) hard to describe/model due to existence of many data formats, described in much different languages, that can share (or not) the same modelling principles, and that can be interrelated in many ways with one another. This qualifies interoperability in the IoT as a problem of complex nature! We therefore need some novel approaches and comprehensions for dealing with the dynamic and complex interoperability of the IoT and also making sure that it endures, that it is sustainable! To this, we advocate the needed of a framework for interoperability that especially targets the Internet of Things taking on its specifics and constraints. This framework can (and should) learn from the best-of-breed interoperability solutions from related domains (e.g. ATHENA Interoperability Framework), to take the good approaches and principles of these while acknowledging and addressing the differences and particulars that the IoT poses. Talk will go about outlining some key aspects that an envisioned framework for interoperability in the Internet of Things should tackle.
