In IoT environment, large amount of data can be collected by various sensors, and the collected data can be processed to create new values. On the other hand, in order to provide the robot services to users, context information is required for recognizing the surrounding situational information. However, each sensor gives a single value as context information, so it is difficult to express the surrounding...
IEEE 802.11ah task group has developed a new wireless local area network (WLAN) technology, sub 1GHz (S1G) WLAN, for future Internet of Things (IoT) environments. Because of the superior propagation feature of S1G frequency band, S1G WLAN can provide very long transmission range, wild coverage, and support more than 8000 devices. In order to alleviate the high collision probability raised in the dense...
Sensory data should be converted into meaningful situational information so that context-aware system can provide various robot services for users on IoT environments. Context-aware system gathers sensor data from the natural environment, which is converted to sensory data and abstracted as situational data to provide robot services. On robot runtime environment, context-aware system is required to...
