Deployment of heterogeneous wireless networks is spreading throughout the world as users want to be connected anytime, anywhere, and anyhow. Meanwhile, users are increasingly interested in multimedia applications such as audio, video streaming and Voice over IP (VoIP), which require strict Quality of Service (QoS) support. Provisioning of Always Best Connected (ABC) network with such constraints is...
The maintenance of Quality of Service (QoS) is more challenging issue when the concept of handover diverts from horizontal handover to vertical handover. QoS is defined in terms of throughput, end to end delay, jitter and packet loss etc. In this paper Wi-Fi and WiMAX technologies are focused to form a heterogeneous network environment. The proposed approach performance is measured and analyzed and...
QoS means providing consistent, predictable data delivery service. QoS is dealt with providing real-time (e.g., voice) as well as non-real-time services. Real time services are required to be more dominant over non real time for QoS prospective. In this paper a fuzzy based approach is presented using ns-2 for handover between UMTS and WLAN networks. It has been observed that the results obtained with...
