The energy-delay trade off in the case of 850 tags and the constant algorithm. (a): Energy consumption as a function of the back-off coefficient. (b): Delay as a functions of the back-off coefficient. "Lines with circles" show when the ICW has been selected in order to minimize the delay. The "plain" lines show when the ICW has been selected in order to minimize energy.
