Data fusion or In-network processing methods were often adopted in Wireless Sensor Networks (WSNs) to reduce data communication and prolong network lifetime, which made WSNs application can be described as a set of tasks (sensing, processing) and dependencies among them. Task assignment has become an important problem which needed to be resolved for different tasks assignment caused different energy...
In large-scale grid applications, relationship between VOs is not simple information aggregating for autonomy and visiting security. This paper presents a virtual grid information database (VGID) which implements a hierarchical and distributed information management mechanism. An information model is presented with extensible resource metadata management and hierarchical information organization that...
This paper presents the design and evaluation of a performance control algorithm related with notification service. In notification service systems, the filtering needs much time. In the past few years, there has been much research done on efficient filtering algorithms. We address the problem from another perspective: control the number of events entering the system to guarantee the performance....
