    Sensor networks pose the challenge of distribution of content generated within the network to the origins of requests for this content in an efficient and timely manner. In this paper, we formulate this multiple-source ...

    Contrary to traditional belief, we show in this paper, that for distributed systems non-preemptive scheduling can perform better than preemptive scheduling in the worst case in terms of task schedulability, under certain ...

  • Jayachandran, Praveen; Abdelzaher, Tarek F. (2007-05)
    In this paper, we present a delay composition rule that bounds the worst-case end-to-end delay of a job as a function of per-stage execution times of higher priority jobs along its path, in a multistage distributed system ...

    This paper develops a framework to analyze the latency and delay composition of workflows in a real-time networked aggregation system. These workflows are characterized by different inputs that are processed along parallel ...

  • Iandola, Forrest; Saremi, Fatemeh; Abdelzaher, Tarek F.; Jayachandran, Praveen; Yener, Aylin (International Conference on Information Fusion, 2011-07)
    In networked data fusion systems, results must be produced by end-to-end deadlines. As such, latency is an important attribute contributing to quality-of-information (QoI) in these systems. A key question is how much work ...

    Many scientific disciplines provide composition primitives whereby overall properties of systems are composed from those of their components. Examples include rules for block diagram reduction in control theory and laws ...
