An Admission Control Algorithm based on Effective Capacity in Ultra-Dense Networks

GONG Xiao-di;WANG Wei;ZHU Xiao-rong;Nanjing University of Posts and Telecommunication;  
To meet the growing demand for traffic,ultra-dense network is one of the key technologies for the 5 Gnetwork.In recent years,the number of users and services increase rapidly in the ultra-dense network composed of Long Term Evolution(LTE)small base stations.The paper proposes an access control algorithm based on the cross-layer effective capacity,which can ensure the Quality of Service(QoS)of users and increase the throughput of the network.The algorithm considers the QoS requirements and the channel condition.It also defines the selection factor to determine the accessed LTE small base station.Therefore,load balance can be realized in each LTE small base station resulting in maximum effective capacity of ultra-dense network on the basis of ensuring the QoS of users.The simulation results show that compared with the traditional algorithm,the algorithm proposed in this paper can improve the system capacity significantly while guaranteeing the users' QoS.
