In this article, we present the design of a novel parallel architecture simulator called <i>ParTejas</i>. <i>ParTejas</i> is a timing simulation engine that gets its execution traces from instrumented binaries using a fast shared-memory-based mechanism. Subsequently, the waiting threads simulate the execution of multiple pipelines and an elaborate memory(More)
System monitoring tools serve to provide operators and developers with an insight into system execution and an understanding of system behavior under a variety of scenarios. Many system abnormalities leave a significant impact on the system execution which may arise out of performance issues, bugs, or errors. Having the ability to quantify and search such(More)
In wireless sensor networks, oppugneries can inject false data reports via compromised nodes and launch Denial of Service attacks against legitimate reports. Recently, a number of filtering schemes against false reports have been proposed. However, they either lack strong filtering capacity or cannot support highly dynamic sensor networks very well.(More)
