Real-time dense wired sensor network based on traffic shaping

Abstract

XDense is a novel wired 2D-mesh grid sensor network system for application scenarios that benefit from denselydeployed sensing (e.g. thousands of sensors per square meter). Itwas conceived for closed-loop cyberphysical systems (CPS) thatrequire real-time actuation, like active flow control (AFC) onaircraft wing surfaces. XDense communication and distributedprocessing capabilities are designed such that they enable toextract complex features within bounded time and in a responsivemanner. In this paper we tackle the issue of deterministic behaviorof XDense. We present a methodology that uses traffic shapingheuristics to guarantee bounded communication delays and thefulfillment of memory requirements. We evaluate the model forvaried network configurations and workload, and demonstratethe effectiveness of running real-time applications supported onXDense. Abstract-XDense is a novel wired 2D-mesh grid sensor network system for application scenarios that benefit from densely deployed sensing (e.g. thousands of sensors per square meter). It was conceived for closed-loop cyber-physical systems (CPS) that require real-time actuation, like active flow control (AFC) on aircraft wing surfaces. XDense communication and distributed processing capabilities are designed such that they enable to extract complex features within bounded time and in a responsive manner. In this paper we tackle the issue of deterministic behavior of XDense. We present a methodology that uses traffic shaping heuristics to guarantee bounded communication delays and the fulfillment of memory requirements. We evaluate the model for varied network configurations and workload, and demonstrate the effectiveness of running real-time applications supported on XDense.

Extensive Analysis of a Real-Time Dense Wired Sensor Network Based on Traffic Shaping

“…In extension to the work presented in [18], in this work we evaluate the heuristics proposed using homogeneous and heterogeneous traic sources and compare it with the best efort approach.…”
