Sensor-rich Context Management Frameworks (CMF) for Ubiquitous Systems should be able to continuosly gather raw data from observed entities (e.g., people, surround enviroment) in order to characterize the current situation (i.e., context). However, the energy of sensors can end up, which reduce the ability of CMF for detecting the current situation, directly affecting the availability of context-aware...
Ubiquitous healthcare means healthcare anywhere anytime, a dream not realized in most parts of this world. On the other hand, the cost of healthcare is increasing and may become totally unaffordable in view of the aging population in many countries. Hence, the world is exploring the means to enhance the reach of healthcare at lower cost. The recent developments in wireless sensor devices and applications...
Context-aware systems (CAS) may face context conflicts while collecting context data to support context-aware adaptation decisions. These systems need to implement mechanisms to resolve context conflicts in order to reduce the probability of making erroneous context-aware adaptation decisions. Quality of Context (QoC) indicators can be used to deal with this challenge, ensuring the correct behavior...
In this paper, we focus on the problem of constructing an information gain model for stroke prevention in Ubiquitous Healthcare (U-Health) Wireless Body Area Networks (WBANs). We have constructed an information-based probabilistic relation model among the key indicators and sequenced their data gathering priority and precedence in the WBAN. Then, we constructed a cost function over the energy expenditure...
