Queuing Time Computation Algorithm for Sensor Data Processing in Real-time Ubiquitous Environment

Abstract

The real?time ubiquitous environment is required to be able to process a series of sensor data within limited time. The whole sensor data processing consists of several phases : getting data out of sensor, acquiring context and responding to users. The ubiquitous computing middleware is aware of the context using the input sensor data and a series of data from database or knowledge?base, makes a decision suitable for the context and shows a response according to the decision. When the real?time ubiquitous environment gets a set of sensor data as its input, it needs to be able to estimate the delaytime of the sensor data considering the available resource and the priority of it for scheduling a series of sensor data. Also the sensor data of higher priority can stop the processing of proceeding sensor data. The research field for such a decision making is not yet vibrant. In this paper, we propose a queuing time computation algorithm for sensor data processing in real?time ubiquitous environment.
