Autonomous mobile sensors are employed with ever-increasing frequency, in applications ranging from search and rescue, detection of forest fires, and battlefield surveillance. In this paper, we consider a representative surveillance problem wherein a sparse number of mobile sensors are expected to cover events of interest in a deployment field. Each event appears for a certain time and then disappears...
Coverage control is one of the key problems of research and applications of wireless sensor networks. In this paper, the coverage control problem for hybrid networks which comprise both static and mobile sensors is investigated. A strategy for the discovery and determination of coverage blind spots based on Voronoi diagram is presented. For the situation that there are many blind spots in the same...
Sensing context information and making it available to the people, involved in coordinating a collaborative task, is a preliminary phase in making a system adaptable to the prevailing situation in pervasive environments. However, the diversity of the sources of context information, the characteristics of pervasive environments, and the nature of collaborative tasks pose a stern challenge to the efficient...
This paper introduces a conceptual framework and process that aims to simplify the development of applications for mobile devices. We specialize on the domain of health monitoring by providing a whole system that would allow people to model their own mobile health monitoring applications in a simplified manner without dealing with low-level coding themselves.
The growth in numbers and capacity of mobile devices such as mobile phones coupled with widespread availability of inexpensive range of biosensors presents an unprecedented opportunity for mobile healthcare applications. In this paper we propose a novel approach for situation-aware adaptive processing (SAAP) of data streams for smart and real-time analysis of data. The implementation and evaluation...
Process management systems (PMSs) can be used not only in classical business scenarios, but also in highly dynamic and uncertain environments, for example, in supporting operators during emergency management for coordinating their activities. In such challenging situations, processes should be adapted in order to cope with anomalous situations, including connection anomalies and task faults. This...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
