Studies from Realistic Experiments Effective scanning window If we use p' to denote the uniform detection probability, then, the probability for an arbitrary tag to be identified at least once is 1-(1 /\m The value of m is equal to Tw/Tc, here Tw is the duration in the effective scanning window and tc is the average duration of a query cycle. Moreover, tw is equal to the ratio of the window width w to the moving speed v, hence m=w/v tcStudies from Realistic Experiments • Effective scanning window – If we use p’ to denote the uniform detection probability, then, the probability for an arbitrary tag to be identified at least once is – The value of m is equal to τw/τc, here τw is the duration in the effective scanning window, and τc is the average duration of a query cycle. Moreover, τw is equal to the ratio of the window width w to the moving speed v, hence m = w/(v·τc)
