In this work, we first present an application-initiatedstrategy that aims to control the energy consumption,while simultaneously enhancing the performance of aheterogeneous embedded system. We assess the benefitsof using this strategy by means of a traditional ...

Until recently, the x86 architecture has not permitted classical trap-and-emulate virtualization. Virtual Machine Monitors for x86, such as VMware ® Workstation and Virtual PC, have instead used binary translation of the guest kernel code. However, ...

This dissertation investigates two research problems to protect wireless network topology and routing: (1) designing protocols with configurable overhead to defend against wormhole attacks; (2) designing an intruder identification mechanism ...

In self-organizing ad hoc networks, all the networking functions rely on the contribution of the participants. As a basic example, nodes have to forward packets for each other in order to enable multihop communication. In recent years, incentive mechanisms ...

Data Vortex networks with different routing and forwarding path arrangements are studied. To keep the bufferless routing nodes, the binary tree decoding stages in Data Vortex network are shown to achieve best combined routing performance in throughput ...

Modern Systems-on-Chip (SoCs) allow integrating many different functional cores in the same piece of silicon. Their test requires to take fast decisions in the selection of structures and strategies at different stages of the design flow: early computation ...

This paper develops a new method for prefetching Web pages into the client cache. Clients send reference information to Web servers, which aggregate the reference information in near-real-time and then disperse the aggregated information to all clients, ...

In this paper, a systematic study of the effects of complexity of prediction methodology on its accuracy for a set of real applications on a variety of HPC systems is performed. Results indicate that the use of any single, simple synthetic metric to ...

The characteristics of several commercial and technical workloads on the DEC 7000 AXP system are compared using built-in hardware monitors. The data analyzed include total instructions, cycles, multiple-issued instructions, stall components, cache misses, ...

To obtain infotainment services (e.g., traffic, maps, accidents, weather, etc.) on the roads, vehicle drivers and back-seat passengers may want to use wide-area networks (e.g., GPRS) to download useful information from the Internet when needed. In this ...

An improved radio resource allocation scheme with avoidance of major interferers is proposed and analyzed for the downlink of Fixed Broadband Wireless Access (FBWA) systems with full frequency reuse. The scheme is based on Enhanced Staggered Resource ...

In this paper we propose an optimizing queue scheme for multimedia network communicationswith dynamic priority. Arriving users are classified into two types based on their transmission contents, and they are served by different priority degrees. The ...

In this paper, we apply the load sharing (LS) mechanism proposed in [1, 2] to HARTS, an experimental distributed realtime system [3] currently being built at the Real-Time Computing Laboratory of the University of Michigan.

We present a routability-driven top-down clustering technique for area and power reduction in clustered FPGAs. This technique is based on a multilevel partitioning approach. It leads to better device utilization, savings in area, and reduction in power ...

A mobile ad hoc is a kind of wireless communication network that does not rely on a fixed infrastructure. Clustering of MANET is a vital factor since it forms a virtual backbone of the network. A K-Hop Weighted Dominated Clustering algorithm is proposed ...

Real-time scheduling on processors that support dynamic voltage and frequency scaling is analyzed. The Slacked Earliest Deadling First (SEDF) algorithm is proposed and it is shown that the algorithm is optimal in minimizing processor energy consumption ...

Energy efficiency has proven to be an important factor dominating the working period of WSN surveillance systems. Intensive studies have been done to provide energy efficient power management mechanisms. In this paper, we present PAS, a Prediction-based ...

Active restoration (AR) is a novel lightpath restoration scheme proposed recently to guarantee a certain degree of survivability in WDM optical networks with a reasonable tradeoff between capacity requirement and restoration time. In this paper, we conduct ...
