Sensing coverage is a critical issue in sensor network deployments. We propose a novel scheme to maintain the sensing coverage in sensor networks, which we call CASS (Coverage-Aware Self-Scheduling). Different from the existing work on coverage maintenance, CASS probabilistically schedules sensing activities according to the sensor’s contribution to the sensing coverage of the whole sensor netw...

Context aware software systems (CASS) are becoming pervasive in our lives. Nevertheless, it is not clear whether traditional (nocontext aware) software testing techniques are adequate for testing CASS. Therefore, a quasi systematic literature review was used to identify 11 relevant sources that mentioned 15 problems and 4 proposed solutions, which were analyzed and classified into 3 groups of c...

there are two dominant approaches to describe and understand the anatomy of complete health and well-being systems internationally. yet, neither approach has been able to either predict or explain occasional but dramatic crises in health and well-being systems around the world and in developed emerging market or developing country contexts. as the impacts of such events can be measured not simp...
