Study on call admission control model of ring wireless networks
Yun Liu · Journal of Zhengzhou University of Light Industry · 2012
In the orthogonal frequency division multiplexing wireless network(OFDM),when the user close to the edge of the base station coverage area,if you want to switch the call,the traditional queuing models switching have a higher failure rate.A new call admission control model based on the ring was established in a coverage area with cover of the base station,cellular will set in concentric circles,though the amount of resources required to establish the cell balance equation of the mobile users,to reduce switch failure rate.The simulation results showed that the model reduces switch failure rate in the protection channel,and improves resource utilization.
