Adaptive QoS Provisioning for Non-Real Time Services in Heterogeneous Wireless Networks

In this paper, the authors introduce a novel adaptive QoS provisioning for non-real time services in heterogeneous wireless networks. The concept is proven via simulation analysis in integrated environment with 3G and IEEE 802.11 networks. They introduce a novel adaptive module that provides the best QoS and lower cost for a given service by using one or more wireless technologies at a given time. The performance of the algorithm is evaluated using simulation with dual-mode mobile stations. The analysis of this concept has shown overall better performances and QoS provisioning for different multimedia services in a variety of network conditions in heterogeneous wireless/mobile environment.
