This paper investigates an optimal traffic rate allocation method for multi-stream aggregation over heterogeneous networks that deals with effective throughput aggregation over two or more heterogeneous links. The heterogeneity and the dynamics of radio is considered as an important factor for performance improvement by multi-stream aggregation. Therefore, in our model, the networks are represented by different queuing systems in order to indicate networks with opposite QoS provisioning, capacity and delay variations. Furthermore, services with different traffic characteristics in terms of QoS requirements are considered. The simulation results show the advantages of our model compared to traditional schemes for bandwidth aggregation.
