A short-range unlicensed network is intended to coexist with a strong licensed link. It is assumed that nodes' density of the primary network is much lower than that of the secondary one. Each node implements an energy-based probabilistic access scheme powered with nature and/or RF energy harvesting. The goal is to decide a criterion for each nodes' access based on a Markov chain under some constraints on the battery finite capacity and the maximum admissible interference on the primary network link. The proposed setup will be simulated in Matlab in order to evaluate and op
