We propose a novel work partitioning technique, Image Layer Decomposition (ILD), designed specifically to support distributed real-time rendering on commodity clusters. ILD has several advantages over previous partitioning algorithms for our targeted environment, including its compatibility with the use of hardware graphics accelerators, decoupling of communication bandwidth requirement from sc...

Mobile nodes that change their connection point dynamically, are deployed in networks for communication with aircraft, boats, trains and cars. These mobile nodes move together and share the same mobility properties. This paper addresses an efficient location management scheme based on collaboration of mobile nodes to a mobile network. In our proposed scheme, we address the efficient location ma...

In this papec we propose a domain decomposit ion scheme that seeks to minimize totalparallel execution time by considering the relative importance of two competing concerns balancing the load and minimizing communication -for a particular application and architecture. A simulated annealing approach is used to optimize an objective function with components that measure both load balance and comm...

In both industrial and domestic environments, there will be a large increase of wireless communication systems. The density of wireless devices and need of additional bandwidth is expanding which is increasing the wireless interference. Interference emerges from unintended radiators is the main cause of degrading the Electromagnetic Compatibility and wireless communication performance in near f...

In digital communications, fixed, chaotic, and random waveforms are used. Although the theory of fixed waveform communications is well established, its generalization to include chaotic and random carriers has not yet been carried out. The lack of an exact model prevents the optimization of chaotic and random communication systems. Introducing the Fourier analyzer concepts, this paper develops ...

The system captures and analyzes the ECG signals in real time through a low cost embedded development board. The system can detect cardiac abnormalities with high precision. One of the objectives at the...

As CMOS technology scales to deep-submicron dimensions, designers face new challenges in determining the proper balance between aggressive high-performance transistors and lower-performance transistors to optimize system power and performance for a given application. Determining this balance is crucial for battery-powered handheld devices in which transistor leakage and active power limit the a...

In this paper, we present and analyze a number of interconnect architectures for reconfigurable systems targeting applications in the areas of wireless communication and multimedia processing. Several interconnect architectures suitable for heterogeneous elements are proposed and then a methodology to evaluate the architectures is described. The results indicate that the hierarchical generalize...

This paper provides an experimental and analytical evaluation of the Client-Server, Remote Evaluation and Mobile Agent communication paradigms. Our purpose is that of identifying the environmental situations in which such paradigms should be preferred or combined in order to optimize the performances of a distributed system. The scenario selected for the analysis is the Information Retrieval on...

We present the novel concept of Pipelets: self-organizing stages of software pipelines that monitor their computational demands and communication patterns and interact to optimize the performance of the application they belong to. They enable dynamic task remapping and exploit application-specific properties. Our experiments show that they improve performance by up to 31.2% compared to state-of...
