异构无线网络中基于业务转移和接入控制的混合负载均衡
Hybrid Load Balancing Algorithm Based on Service Transformation and Admission Control in Heterogeneous Wireless Networks
摘要
Abstract
Aiming at working out the problem of existing load balancing algorithms that failed to consider the combination of load transfer scheme and call admission control scheme in heterogeneous wireless networks, a hybrid load balancing algorithm is proposed. Firstly, an adequate number of ongoing calls can be transferred from overload cells into the overlapping ones with light workload according to the load rate of each cell and terminal mobility. Then, new calls with different priorities are differential served by means of resource reservation and preemptive priority based call admission control strategy. Simulation results show that the algorithm can guarantee the system resource utitation and the QoS of real time and non-real time services, as well as decrease the system call blocking probability and handover rate effectively compared to the reference algorithms.关键词
