To solve the different Quality of Services(QoS)for data flows over wireless networks

based on the classical LV(Lotka-Volterra)model

this paper proposes a bio-inspired competition models for differential QoS services.The mapping relationship between wireless networks and ecosystem is set up.Traffic flows will be assigned with different priorities according to IEEE 802.11e protocol

and its sending rate can be calculated as the output of the proposed model through limited iterations(e.g

instantaneous value and steady-state value).The simulation results reveal that the proposed model achieves better performance than EDCA in terms of adaptability

scalability and fairness.
