A Novel Cross-Layer Vertical QoS Mapping Mechanism in Heterogeneous Networks
Xiang-ying Dong, Xue-qun Wang, Ping Wang, Mei Na Song · 2012
QoS parameter mapping is a key technology with respect to guaranteeing QoS of business in heterogeneous networks dynamically. This paper studies a method for guarantee necessary End-to-End QoS for user satisfaction, focusing on the problem of quality of service (QoS) mapping between layers in a cascade. Due to the dynamic mapping of parameters, the consistency between user and network is guaranteed. In this paper, we proposed a novel cross-layer QoS mapping mechanism on the basis of a multiple linear regression. The mechanism realizes the vertical mapping of QoS parameters between user-level and transport-level. Hence the QoS connection is constructed between networks to ensure the end-to-end QoS of business. The simulation results show that our mechanism can greatly improve the satisfaction of users without reducing the mean throughput.
