There are two categories of sensors for healthcare application. The first category is called ambient sensors. Ambient sensor is used to monitor the general activity patterns based on spatial and temporal information processing. Examples of ambient sensors are fall detectors, door monitors, bed alerts, pressure mats, smoke and heat alarms etc. More recent works on […]
Amount of different devices (sensor nodes) interacting in an IOT environment is big. These devices must be able to connect to each other despite their different network technologies. Furthermore, the devices also require service discovery procedures as well as means to enforce semantic compatibility between devices. These requirement create a demand for a software layer […]
Wireless sensor networks is a wireless network that consists of spatially distributed autonomous devices using sensors to monitor environment condition such as temperature, humidity, sound, image and etc.
Internet of Things refers to the virtual interconnection of identifiable objects which is like the Internet-structure. The identifiable objects (nodes) could be any devices around us that contains embedded technology which can sense and communicate with its external environment. This interconnection forms a network of billion physical nodes, and by the year of 2020 it […]
