Title: QoS in Next Generation Wireless Networks
Abstract:
Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. Quality of experience (QoE) is a subjective measure of a customer's experiences with a service. The "best effort" Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer QoS/QoE for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed services as well as high rate communications.
The emerging Internet architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.
This keynote covers to the issues of provisioning in heterogeneous networks and Internet access over future wireless networks. It discusses the characteristics of the Internet, mobility and provisioning in wireless and mobile IP networks. This keynote also covers routing, security, baseline architecture of the inter-networking protocols, end to end traffic management issues and QoS for Mobile/Ubiquitous/Pervasive Computing users.
