摘要：Time-critical wireless application in up-and-coming scheme coordination, such as e-healthcare andelegant grids, have be drawing growing concentration in both manufacturing and academic world. The show nature ofwireless channel inescapably exposes such request to jamming attacks. However, obtainable method to set separatelyand detect congestion attacks cannot be applied straight to time-critical network, whose communiqué traffic modeldiffers from conservative models. We aim at model and detect overcrowding attack against time-critical traffic. Webring in a new metric, message cancellation ratio, to quantify the presentation of time-critical application. A key insightthat leads to our modeling is that the behavior of a jammer who attempts to disrupt the delivery of a time-criticalmessage can be exactly mapped to the behavior of a gambler who tends to win a gambling game. We show via thegambling-based model and real-time experiment that there in universal exists a phase change occurrence for a timecriticalrequest under jamming attack: as the likelihood that a small package is jammed increase from 0 to 1, themessage cancellation ratio first increase slightly (even negligibly), then increases dramatically to 1. Based on logicaland new results, we further plan and put into practice the JADE (Jamming Attack Detection based on Estimation)system to attain efficient and healthy jamming discovery for time-critical wireless network
