Ecology-inspired Admission Control scheme in heterogeneous wireless Networks

Different radio access technology vary with communication parameters, such as mobility, coverage and bandwidth etc. Joint Admission Control (JAC) technology therefore is put forward to make the different Radio Access Networks (RANs) work together. This paper proposes a distributed JAC scheme based on the ecology theory in heterogeneous wireless network. It establishes a mapping relationship of ecological competition and heterogeneous radio resources management, and adopts the Gause-Lotka-Volterra (GLV) model to predict the heterogeneous network traffic. Based on the mapping relationship and GLV model, the network parameters can be adjusted to achieve a balanced traffic state for different RANs. In the simulation, we evaluate the network traffic and blocking probability performances. Results show that the ecology-inspired JAC scheme can balance the traffic, reduces the networks competition effect, and moreover makes the profits by different operators jointly.
