Abstract
The number of physical resources, such as embedded sensors, actuators, and processors, that are connected to the Internet is increasing, leading to the formation of the Internet of Things. We argue that the discovery of adequate resources is difficult but important for open IoT services that use various IoT resources among various protocols and platforms. To discover appropriate resources for services among many resources, discovery considering live data is important. In contrast to current Web search engines, live data are dynamic, so it is difficult to adopt current architectures. In this paper, we discuss how live data search can be enabled with a distributed buffer mechanism and propose a live data search architecture for IoT.
