WebbWe prove several relationships among Pareto-Zipf's law, Gibrat's law and the condition of detailed balance. As a consequence, we show that the distribution of growth rate possesses a non-trivial relation between the positive side of the distribution and the negative side, through the value of Pareto index, as is confirmed empirically. WebbAs the Internet of Things devices are deployed on a large scale, location-based services are being increasingly utilized.
