A Novel Cross-Layer Vertical QoS Mapping Mechanism in Heterogeneous Networks

Abstract

QoS parameter mapping is a key technology with respect to guaranteeing QoS of business in heterogeneous networks dynamically. This paper studies a method for guarante 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 netweork 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 userlevel 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.

A Novel QoS Mapping Mechanism in Integrated UMTS/WLANs

“…Furthermore, these QoS mapping methods in the related papers are all fixed one-one mapping, which means that there is only one servicing network mapped into one target network. However, few literatures discuss a generalized QoS mapping method in heterogeneous networks, and few papers consider the end-to-end QoS of users from a whole view point [17]. In the future, a variety of applications may require fine-granular QoS and new applications will need more fine-granular QoS.…”
