ImageFlow is a plugin that allows the generation and execution of macros in ImageJ based on the visual programming paradigm. Image processing steps are described by connected nodes on a workspace. Specifying image-processing algorithms corresponds to visually editing block diagrams (the workflow of successive processing steps). This abstraction makes it very flexible and easy to save, restore a...

Data-Centric approaches based on data-aggregation strategies and in-network processing has been shown to be an interesting strategy to improve scalability conditions, optimize information dissemination, minimize redundancy and increase network lifetime in wireless sensor networks (WSN). In critical-mission WSN applications, secure in-processing strategies translates to both efficient, reliable,...

This paper proposes a method for optimized placement of query processing elements in a distributed stream processing platform consisting of several computing nodes. We focus on the case that multiple users run different continuous Complex Event Processing (CEP) queries over various event streams. In times of increasing event frequency it may be required to migrate parts of the query processing ...

Systems for estimating human motion using acceleration sensors present the following two problems: 1) advanced analysis and processing of sensor data are difficult because of resource limitations of sensor nodes; and 2) such analyses and processes burden the network because numerous sensor data are sent to the network. The authors’ proposed method described herein for sensor data analysis and p...

Network dilation is a way of offering system families, at a range of sizes and computational powers, which share an underlying communication architecture and routing algorithm. We consider indirect networks that connect processing nodes via intermediate switch nodes. In the simplest such indirect networks, there is a switching network of some regular topology, where each switch is connected to ...

Traditional wireless networks focus on transparent data transmission where the data are processed at either the source or destination nodes. In contrast, the proposed approach aims at distributing data processing among the nodes in the network thus providing a higher processing capability than a single device. Moreover, energy consumption is balanced in the proposed scheme since the energy inte...

In this paper, we present an energy dissipation model for reconfigurable systems in which FPGAs have the property of online reprogramming. The proposed system contains regular nodes and one control node. Each regular node contains both CPU capable of software processing, and FPGA unit which after being programmed with bitstream serves as the hardware processing parts. Nodes are connected in som...

Analyzing large graphs are crucial to a variety of applications domains, like personalized recommendations in social networks, search engines, communication networks, computational biology, etc. In these domains, there is a need to process aggregation queries over large graphs. Existing approaches for aggregation are not suitable for large graphs, as they involve multi-way relational over gigan...

designing wireless sensor networks should meet appropriate parameters such as quality of service (qos) defined by different users. the variable physical conditions of the environment, processing and transmission power limitations and limited communication capabilities are the most important obstacles that influence qos parameters such as throughput, delay, reliability and network lifetime. the ...

Advances in medical sciences with other fields of science and technology is closely casual profound mutations in different branches of science and methods for providing medical services affect the lives of its descriptor. Wireless Body Area Network (WBAN) represents such a leap. Those networks excite new branches in the world of telemedicine. Small wireless sensors, to be quite precise and calc...
