A semantic interoperability architecture typically consists of collaborating heterogeneous networks and devices with different availability of resources such as bandwidth, processing power, memory, storage and energy. Due to utilization of ontology based information representation and communication formats, a gateway approach for achieving semantic interoperability becomes complex and may require long processing times. Especially when the constraints on acceptable response times in services with user interaction are considered, the end-to-end delay becomes an important performance criterion. In this paper, we make an analysis of the processing delay per device and the transmission delay per hop in a heterogeneous smart network. We identify the processes and the transmission links that dominate the end-to-end delay based on our experiments on a power-managed smart lighting scenario.
