Sensor Deployment and Relocation:A Unified Scheme

Journal of Computer Science & Technology 2008年第3期23卷 400-412页

作者： Michele Garetto Marco Gribaudo Carla-Fabiana Chiasserini emilio Leonardi Dipartimento di Informatica Università di TorinoTorinoItaly Dipartimento di Elettronica Politecnico di TorinoTorinoItaly

Sensor networks are envisioned to revolutionize our daily life by ubiquitously monitoring our environment and/or adjusting it to suit our needs. Recent progress in robotics and low-power embedded systems has made it possible to add mobility to small, light, low-cost sensors to be used in teams or swarms. Augmenting static sensor networks with mobile nodes addresses many design challenges that exist in traditional static sensor networks. This paper addresses the problem of topology control in mobile wireless networks. Limitations in communication, computation and energy capabilities push towards the adoption of distributed, energy-efficient solutions to perform self-deployment and relocation of the nodes. We develop a unified, distributed algorithm that has the following features. During deployment, our algorithm yields a regular tessellation of the geographical area with a given node density, called monitoring configuration. Upon the occurrence of a physical phenomenon, network nodes relocate themselves so as to properly sample and control the event, while maintaining the network connectivity. Then, as soon as the event ends, all nodes return to the monitoring configuration. To achieve these goals, we use a virtual force-based strategy which proves to be very effective even when compared to an optimal centralized solution. We assess the performance of our approach in the presence of events with different shapes, and we investigate the transient behavior of our algorithm. This allows us to evaluate the effectiveness and the response time of the proposed solution under various environmental conditions.

Coronary heart disease incidence and competing risks： an important issue

作者： Paolo emilio Puddu Peter Louis Amaduzzi Beatrice Ricci Department of Cardiovascular Respiratory Nephrological Anesthesiological and Geriatric Sciences Sapienza University of Rome italy Department of Experimental Diagnostics and Specialty Medicine Univerity of Bologna Italy

The estimation of lifetime morbid events is not a rare presentation of relatively old and of more recent epidemi- ological investigations, accompanied by evaluating rates, risks and predictors （more in general determinants or risk factors）. However, when the follow-up period is very long and Kaplan-Meier survival curves are adopted, or Kaplan- Meier-based more complex models such as Cox＇s analysis are used, clinical （or epidemiological） reality may well be distorted since by these survival methods risks tend to be overestimated, whereas survival tends to be reduced.

Cooperating CoScheduling:A Coscheduling Proposal Aimed at Non-Dedicated Heterogeneous NOWs

引用

Journal of Computer Science & Technology 2007年第5期22卷 695-710页

作者： Francesc Giné Francesc Solsona Mauricio Hanzich Porfidio Hernández emilio Luque Department of Computer Science Universitat de Lleida Spain Department of Computer Architecture & Operating Systems Universitat Autònoma de Barcelona Spain

Implicit coscheduling techniques applied to non-dedicated homogeneous Networks Of Workstations （NOWs） have shown they can perform well when many local users compete with a single parallel job. Implicit coscheduling deals with minimizing the communication waiting time of parallel processes by identifying the processes in need of coscheduling through gathering and analyzing implicit runtime information, basically communication events. Unfortunately, implicit coscheduling techniques do not guarantee the performance of local and parallel jobs, when the number of parallel jobs competing against each other is increased. Thus, a low efficiency use of the idle computational resources is achieved. In order to solve these problems, a new technique, named Cooperating CoScheduling （CCS）, is presented in this work. Unlike traditional implicit coscheduling techniques, under CCS, each node takes its scheduling decisions from the occurrence of local events, basically communication, memory, Input/Output and CPU, together with foreign events received from cooperating nodes. This allows CCS to provide a social contract based on reserving a percentage of CPU and memory resources to ensure the progress of parallel jobs without disturbing the local users, while coscheduling of communicating tasks is ensured. Besides, the CCS algorithm uses status information from the cooperating nodes to balance the resources across the cluster when necessary. Experimental results in a non-dedicated heterogeneous NOW reveal that CCS allows the idle resources to be exploited efficiently, thus obtaining a satisfactory speedup and provoking an overhead that is imperceptible to the local user.

Hardware-programmable optical networks

引用

Science China(Information Sciences) 2016年第10期59卷 21-32页

作者： Shuangyi YAN emilio HUGUES-SALAS Yanni OU Reza NEJABATI Dimitra SIMEONIDOU High Performance Networks Group University of Bristol

For future multi-dimensional optical networks, vast network resources provided by space division multiplexing and wavelength division multiplexing technologies, require new network architectures to scale up current network functions. The huge switch-granularity range requires a more dynamic way to deploy network resources. In this paper, we proposed a hardware-programmable optical network which deploys network resources according to incoming traffic requests. The proposed network supports node function programmability and node architecture adaptability, which are critical for dynamic function and resources deployments. Architecture-onDemand based node architecture adapts node architectures and also enables network function programmability by incorporating with several flexible node functions. Other enabling technologies, such as ubiquitous power monitoring and dynamic optical power management, assures the programmable optical node work *** on all these technologies, we established a hardware-programmable optical network testbed. Several use cases were demonstrated successfully, such as dynamic power equalization and optical debugging. These work verified the feasibility of hardware-programmable optical network, which dynamically allocate network resources for service provision. The proposed hardware programmable optical network will lead to a better hardware utilization and provide a possible solution for the future multi-dimensional optical network.
