Wireless sensor networks are a fast-growing class of systems. They offer many new design challenges, due to stringent requirements like tight energy budgets, low-cost components, limited processing resources, and small footprint devices. Such strict design goals call for technologies like nanometer-scale semiconductor design and low-power wireless(More)
One or the main challenges in adoption and deployment of wireless networked sensing applications is ensuring reliable sensor data collection and aggregation, while satisfying the low-cost, low-energy operating constraints of such applications. A wireless sensor network is inherently vulnerable to different sources of unreliability resulting in transient(More)
— One of the main challenges in wireless sensor networks is to provide low-cost, low-energy reliable data collection. Reliability against transient errors in sensor data can be provided using the model-based error correction described in [1], in which temporal correlation in the data is used to correct errors without any overheads at the sensor nodes. In(More)
—Increasing interest in sensor networking and ubiquitous computing has created a trend towards embedding more and more intelligence into our surroundings. This enables thin wireless clients to support powerful applications by using processing resources that are available around them. One of the major challenges is how to schedule both the embedded computing(More)
Service-based systems are distributed systems which have the major advantage of enabling rapid composition of distributed applications, regardless of the programming languages and platforms used in developing and running different components of the applications. In these systems, various capabilities are provided by different organizations as services(More)
Digital rights management (DRM) system is widely used to restrict the illegal content consumption. However, to achieve security and accountability, the system loses privacy. In addition, multiparty multilevel (MPML) DRM system maintains single private key generator (PKG), which completely eliminates online lookup in a large network. In this paper, we(More)
With the universal adoption of mobile communication devices for many common computing applications like email and web access, there is a growing demand to use these devices for richer applications that require high computing power. This paper looks at a way of enabling thin wireless clients to support powerful applications by using processing and networking(More)
abStraCt Service-based systems have many applications, such as e-business, health care, and homeland security. In these systems, it is necessary to provide users the capability of composing services into workflows providing higher-level functionality. In dynamic service-oriented computing environments, it is desirable that service composition is automated(More)
