    Achieving scalability for job centric monitoring in a distributed infrastructure
    (ARCS 2012 Workshops, 2012) Hilbrich, Marcus; Müller-Pfefferkorn, Ralph
    Job centric monitoring allows to observe jobs on remote computing resources. It may offer visualisation of recorded monitoring data and helps to find faulty or misbehaving jobs. If installations like grids or clouds are observed monitoring data of many thousands of jobs have to be handled. The challenge of job centric monitoring infrastructures is to store, search and access data collected in huge installations like grids or clouds. We take this challenge with a distributed layer based architecture which provides a uniform view to all monitoring data. The concept of this infrastructure called SLAte and an analysis of the scalability is provided in this paper.

    Adaptive content distribution network for live and on-demand streaming
    (ARCS 2012 Workshops, 2012) Miyauchi, Yuta; Matsumoto, Noriko; Yoshida, Norihiko; Kamiya, Yuko; Shimokawa, Toshihiko
    We have proposed an adaptive content distribution network (CDN), FCAN (Flash Crowds Alleviation Network), which changes its structure dynamically against a flash crowd, that is a rapid increase in server load caused by a sudden access concentration. FCAN in our preceding studies responds only to static content delivery. In this paper, we extend FCAN to alleviate flash crowds in video streaming. Through some experiments, we confirmed that FCAN for video streaming is effective to alleviate flash crowds.

    An anonymous efficient private set intersection protocol for wireless sensor networks
    (ARCS 2012 Workshops, 2012) Moldovan, George; Ignat, Anda
    We present an efficient protocol which, under certain assumptions, provides a suitable level of security and anonymity in the ideal cipher model when computing the intersection of two private data-sets containing lists of elements from a large domain. The assumptions are that each node is pre-loaded with a set of pseudonyms, signed by the network's trusted authority; that the cardinality of each data-set is globally known. Our protocol first establishes a secure, trusted connection between two partners, then uses lightweight, symmetrical key operations for encoding and privately comparing the elements of two sets. Given a cryptographically secure symmetric encryption scheme, our protocol is safe for both semi-honest and malicious adversaries. The primary target platform for this protocol are Wireless Sensor Networks (WSNs), specifically those used in Ambient Assisted Living (AAL) scenarios, which almost entirely consist of a heterogeneous mix of devices, providers and manufacturers.

    Ant colony optimization for dynamic traveling salesman problems
    (ARCS 2004 – Organic and pervasive computing, 2004) Silva, Carlos A.; Runkler, Thomas A.
    This paper addresses the optimization of a dynamic Traveling Salesman Problem using the Ant Colony Optimization algorithm. Ants are social insects with limited skills that live in colonies able to solve complex problems. The intelligence of the global society arises from self organization mechanisms, based on the indirect communication between individuals through pheromones. The routing problem here presented is a typical case that requires a self organization type of algorithm, in order to cope with the problem dynamics. The simulation results show how the ant colony optimization is able to solve the different possible routing cases.
